Few days ago Apple started detecting jail-broken devices via iBooks denying access to books if found positive, to counter this sn0wbreeze v2.2R3 is now available for download patching the gap Apple used to detect sn0wbreeze jailbroken phones.

Recently Apple imposed minimum baseband restrictions on iOS restores, popular Windows jail-breaking utility Sn0wbreeze will soon be featuring a new option ‘Baseband Preservation Mode’ in the upcoming v 2.2 release - which basically allows users to upgrade to newer iOS versions preserving their basebands but not jail-breaking as in the usual case.

iPhone Dev Team is once again in the news for posting a much-awaited update to their redsn0w iOS jail-breaking utility, the latest redsn0w 0.9.7 Beta 2 release is strictly for testers fulfilling the promised untethered jailbreak for iPhone, iPad and iPod Touch running iOS 4.2.1.

Developer of popular TinyUmbrella application has confirmed an interesting development on Apple's strategy to block carrier-unlockers, starting from recently released iOS 4.2.1 Apple seem to be enforcing a minimum baseband (bootrom) version requirement for users trying to upgrade their firmware. Users have resorted on tools like TinyUmbrella and Sn0wbreeze to update their device firmware to latest version keeping an older unlockable baseband version letting them enjoy the newest Apple iOS version while retaining a carrier-unlocked phone, this has changed for now until someone hacks their way-in finding a new way to get around this. The worst part is that if you try to use an older baseband updating to stock iOS 4.2.1 you will be stuck in recovery mode with no option but to restore back to iOS 4.1 or iOS 4.2.1 which means no carrier-unlock.

Apple iOS Firmware Update 4.2.1 is live now available for public downloading, the new build fixes several security issues and comes bundled with new added features and improvements.

A complete list of new changes and additions is as follows.
