As expected whizkid GeoHot's iPhone carrier unlock for baseband 05.11.07 dubbed blacksn0w is live now and user can now safely upgrade to the latest iPhone OS 3.1.2 having baseband 05.11.07 via iTunes and still get the carrier-unlock using blacksn0w and jailbreak through Blackra1n RC3 utility.

The latest Blackra1n release is available for both Windows and Mac getting the job done in just 15 seconds, it now also supports Hacktivation which means now you don't need the official SIM to activate your iPhone using iTunes.

If you keep up with latest tech-news you must have heard about the Palm Pre and Apple tussle regarding support for non-apple devices in iTunes, If you are also looking for an iTunes replacement for syncing your music collection with non-apple devices or simply don't like using iTunes we had shared free iTunes alternatives which got the job done easily like WinAmp iPod Plugin and iTunes Agent; but all new utility DoubleTwist takes this to a whole new level by providing syncing support for wider range of devices and comes equipped with music purchasing facility via Amazon® MP3 Store (coming soon) posing a direct competition to Apple iTunes music store.

DoubleTwist supports both Windows and MAC platforms letting users choose and sync pictures, videos, music or iTunes playlists with hundreds of devices like Apple iPhone, iPod, Palm Pre, Android phones, BlackBerry, Sony PSP, Archos 605, Sony Ericsson Walkman & Cybershot phones, Nokia N & E Series phones, Windows Mobile 5.0/6.0 platform devices, LG's Viewty and Shine, Motorola (V9 and V3xx)/most Razr phones, Amazon Kindle, Nintendo DSi, most digital cameras and flash-memory-based camcorders.

iPhone Dev Team's latest PwnageTool v 3.1.4 for Mac OS X is now available for download adding jailbreak support for newest iPhone OS 3.1.2 on iPhone 3G/3G(S) and iPod Touch 1G/2G, sadly, similar to the previous PwnageTool release this version is also MAC only for now, however Windows users need not to worry as they can jailbreak their iDevices using recently launched Blackra1n.

Users having jailbroken devices need not to enter the DFU mode and simply need to create a custom IPSW file using PwnageTool v 3.1.4 and restore it from iTunes, this will update the device to latest firmware version keeping the Baseband unlockable so you can enjoy your device freely.
