During the day, we're mild-mannered tech bloggers, wearing glasses and looking moody in our vast, yet innocuous, Crave penthouse. But at night, we fight crime. We take on the persona of a creature of the night, black, terrible, shadowy -- we become the Ghost Pigeon.

To protect our loved ones, we have to keep our secret identity super-duper seekrit. That means hiding our calls and texts to the police commissioner, especially when we send him MMS messages with videos of us collaring a miscreant.

Luckily, just for people like us there's Ghost Pigeon software, a secret-phone-within-a-phone, which will hide your texts, MMS messages and calls.

Ghost Pigeon is invisible on the phone -- there's no icon in the menu. Instead, you launch the application by typing in a password. We installed Ghost Pigeon on our Nokia N95 8GB, and although it's visible in the list of installed apps, its name is well disguised.

Sure, you got an iPhone to look cool on the train on to work, but don't forget that it does more collect face grease and make amusing fart noises. So whether it's from the patio of your Tuscan villa or from your sweaty commuter-packed carriage, this collection of iPhone apps will transform your iPhone into an office. Some are paid for, but many are free, and all links will take you direct to the iTunes App Store.

On its various digital channels, ITV shows three hours of Jeremy Kyle every day. That means there are 15 hours worth of glorious chav-baiting each week that we can't watch because we're busy writing terrific stories here. So what we need is some sort of device that can store massive amounts of non-ironic velour tracksuits and chunky gold identity bracelets. Luckily, Sagem has come to the rescue with a 500GB, twin-tuner Freeview+ PVR.

The ability to record the very scrapings of society's barrel is just the start. Sagem claims the 67500T is also eco-friendly, which means we'll still have a planet for people to argue on in 100 years.

Today is the 37th anniversary of the first Gay Pride march in England. More relevantly to our concerns, it's also the day new EU regulations come into effect that could slash the cost of using your mobile phone while abroad by more than half. So, a good day to be gay and on holiday.

There's a short version and a long version, after the jump.

Our favourite Apple joke is that the Mac has one game -- Marathon -- and Apple users are still playing it 250 years after it was first released. Horrifically, it seems we won't be able to use this time-honoured material much longer, as Apple is on its way to becoming one of the leaders in mobile gaming -- all because of the iPhone. It's not the only smart phone platform, of course, and Google's Android OS is building up a fine library of its own.

We've put together a list of the best value (free) games you can lay your hands on at the moment for Android. If you've got one of the rapidly expanding number of Android phones, this should help you get more out of it.

After taking a medical leave of absence in January, Steve Jobs on Monday officially resumed his work as chief executive of Apple.

"Steve is back to work," Apple spokesman Steve Dowling, told Bloomberg News. Jobs will be working at Apple's headquarters in Cupertino, California, for "a few days a week", and working from home on the rest, according to the report.

Jobs was initially said to be taking a break from work to focus on recuperating from a hormone imbalance. But, in April, he received a liver transplant from a hospital in Tennessee.

The HTC Hero will be made available SIM-free in the UK on 15 July, as shown by its pre-order status on Amazon's UK site.

The Hero will cost £430 through the online retailer. The handset is the first Android-based phone not to be tied exclusively to one operator, and will be available in the UK through Orange and T-Mobile, as well as unlocked and SIM-free.

Amazon put the Hero up for pre-order on 24 June. Orange has said it will sell the handset on contract from early July, and T-Mobile intends to begin sales from mid-July. Neither operator has given more specific timings.

Dell is developing a pocket-sized Internet device using Google's Android operating system that could take on Apple's iPod touch, according to a report in The Wall Street Journal on Monday.

Two people who have seen early prototypes of the device told the newspaper it looks like the touch but is slightly larger. And, like the touch, the device isn't expected to include a phone. The device is considered part of a category of gadgets called 'mobile Internet devices' (MIDs), which are designed to fit into the market between a mobile phone and a laptop or netbook computer.

The device could go on sale as early as the second half of 2009, according to The Wall Street Journal's sources.

The newest version of Sony's PlayStation Portable console -- the PSP Go (pictured) -- isn't even on sale yet, but the company is already looking ahead to what's next, according to Reuters.

The electronics giant is looking into making a combination gadget that would meld its PSP gaming system with the mobile phones made by Sony Ericsson, its joint venture with Swedish electronics maker Ericsson, according to Reuters, which cited the Nikkei business daily.

Sony reportedly plans to put together a team as early as July to begin development of the new device.

One of the hallmark features of the iPhone 3GS is video recording. Waterproofing, however, is not part of the package.

YouTube user KhenaKara was filming some poolside footage on his shiny new iPhone 3GS when disaster struck: the phone slipped out of his hand and into the depths of the swimming pool. Lucky for us, he put the video up on YouTube -- check it out after the jump.

We have to lean out the kitchen window to get a signal in our lead-lined bunker of a flat, so we're interested to hear that Vodafone is releasing a signal booster for people who live in similar mobile-phone notspots.

On 1 July, Vodafone will be the first European network to launch a femtocell -- the Vodafone Access Gateway. Femtocells are modem-sized devices that plug into your home broadband line, boosting the mobile-phone signal in your house.

The Vodafone Access Gateway will allow four simultaneous voice calls at a time, and will support the whole range of Vodafone services on your phone. You'll have to register the mobile numbers that you want to use with the gateway, lest your neighbours attempt to piggyback on your femtocell.

But you'll have to pay for it. You can rent an Access Gateway from £5 per month, or make a one-off purchase for £160. You can also get one as part of a phone contract, starting at £15 per month. You'll also have to pay for, and maintain, your own broadband connection.

HTC has announced a new front end for its Android mobile phones. HTC Sense, which allows you to customise your phone and aggregate your social media, will debut on the HTC Hero, also known as the T-Mobile G1 Touch.

The Hero, with its distinctive curve towards the bottom, features assisted GPS, a digital compass, 3.5mm stereo headset jack and 5-megapixel camera with autofocus. A dedicated search button lets you search Twitter as well as information stored on the phone. Data is saved on microSD cards.

Support for Microsoft Exchange is included out of the box. We're waiting to hear from T-Mobile how this has been achieved, but we're guessing that it's through a pre-installed, third-party application, as the Android operating system doesn't support this natively. As current Exchange apps on the Android Market tend to be paid-for, and some are of dubious quality, it should save you money in the long run.

The handset includes a gravity sensor. If you think about it, though, every phone has one of those: drop it into concrete and you'll quickly see that, yep, gravity is still there.

There's no doubt that the iPhone 3G S is the current king of touchscreen smart phones, but you may have to pawn your fillings to get one, and we've hardly got any left after shelling out for the iPhone 3G only a year ago. Furthermore, with Apple giving away most of the goodies in a free software upgrade, is it worth buying out your contract and selling your sisters online to get a 3G S?

A bunch of CNET readers around the world, and many more on Apple's Discussion boards, have reported a bevy of problems -- some major, some minor -- after upgrading to iPhone OS 3.0 or the iPhone 3G S. We round up the most common and find solutions for them.

LiveJournal blogger HappyWaffle (real name Kevin) recently posted a great story about how he purportedly used Apple's MobileMe service to track down his iPhone, which was stolen while he was at a bar. By using a laptop with a wireless data card, he and his friends used the 'Find My iPhone' service to figure out where it was and managed to get it back from the person who had taken it. They even used Google Translate to alert the thief (in multiple languages) that they would call the police if the device was not returned.

As good as the story is, much of it relies on iPhone owners having certain settings flipped on, as well as the person who has the phone not knowing the right ones to turn off. For one, they can disable all of the MobileMe features by simply yanking the SIM card out or deleting the MobileMe account from the phone.

With the Palm Pre successfully launched in the US, plenty of people want to know when the Mojo software development kit for webOS will be released, so they can get more apps for the smart phone. Now they have an answer -- sort of.

On Friday, Palm updated its Developer Network Blog to let users know that, while eager to open up the SDK to a wider audience, the software and developer services simply aren't ready to support this yet. The company's goal is to release the SDK by the end of summer.

In the short term, Palm said it will expand its early-access programme immediately.

We're sure you know the iPhone's new 3.0 OS has been released, ramping up the phone and its iPod touch brethren with dozens of new features. In fact, our resident Apple fanboy, Ian Morris, has actually conceded that it may be the greatest piece of technology he's ever used.

So, just before we publish our epic full review, let's look at what we think are the five most compelling features the new OS brings to the proverbial table.

Communications minister Lord Carter has put the idea of mobile coverage on the London Underground back on the government agenda -- only months after it emerged a planned Tube mobile trial had been shelved indefinitely.

Back in March, CNET UK's sister site silicon.com revealed Transport for London (TfL) had quietly dropped plans for a six-month mobile Tube trial. The pilot, which was to have considered whether it would be technically and commercially viable for coverage to be extended across the entire Underground network, was shelved after TfL said it had not received any commercially "credible" proposals from the market.

However, in the government's Digital Britain report, unveiled on Tuesday, Lord Carter said there is a need to address "notable gaps" in mobile coverage on transport networks.

Apple issued a warning earlier this week that it doesn't support iTunes synchronisation with "non-Apple digital media players" and that future versions of the software may put an end to any such capability. The announcement was dripping with so much passive aggression it was obvious it was directed at the Palm Pre, which shows up as an iPod when connected to iTunes and allows you to sync non-DRM media to the smart phone.

Palm isn't taking it lying down and has responded to Apple's threats.
