George Hotz (Geohot) continues to show off his iPhone hacking achievements with an untethered jailbreak. He announced the successful experiment on his blog along with posting a video of his iPhone rebooting.

According to Geohot, the entire project took 2.5 days to complete from start to finish. He refuses to set a release date, although the iPad release date of April 3rd is possible. The new jailbreak is supposedly just as easy to run as blackra1n, his previous one-click solution.

If the latest AdMob Mobile Metrics Report can be believed, roughly half of smartphones worldwide are running iPhone OS. The runner up this February is Android, with 24 percent. Symbian is in third place with 18 percent.

Although this is a serious achievement for Apple, the story gets more interesting when comparing the data to the same time period last year. iPhone has boosted its share by 17% over February 2009, while Symbian OS dropped a dramatic 25 percent.

The Apple iPhone has done it again. After winning the first touch screen battle earlier this year, a new robotic test by MOTO Development Group proves that when it comes to accuracy the iPhone can't be beat. For this test MOTO added two more devices to the lineup, the Palm Pre and BlackBerry Storm 2.

Google's Nexus one came in second place, with the Motorola Droid exhibiting the worst performance during the test. Two different sized robotic "fingers" were used at two different pressures to see which screens had the most accurate response. The iPhone showed a little bit of inaccuracy around the edges in the light pressure test, however it was light years ahead of the competition.

In mid-April AT&T Wireless subscribers will have the option of purchasing their own personal 3G cell phone tower. The MicroCell will run $149.99 and is fully compatible with the iPhone 3G and 3GS. The devices will be rolled out in different markets over the next few months.

The MicroCell is a solution for users who have little or no 3G coverage in their home and access to a broadband Internet connection. The device allows users to make calls and send text messages against their AT&T Wireless account using a 5,000 square foot personal 3G network.

Blacksn0w RC2 is now available for those looking to unlock their iPhones running firmware 3.1.3. Beware however, this will not work with the latest baseband version 05.12.07. If you've updated your iPhone to 3.1.3 using Apple's official firmware you are out of luck.

Those updating their jailbroken device to iPhone OS 3.1.3 using PwnageTool 3.1.5 have taken advantage of Apple's battery fixes without altering the baseband from its current unlockable version, 05.11.07. In this case you can now download blacksn0w RC2 from Cydia.
