The new Apple iOS 5.0 is really amazing and has over 200 features with some awesome new prospects like iMessage, new notification center, Wi-Fi synchronization, newsstand, etc. What is really amazing is that it comes integrated with iCloud, a new concept developed by Mr. Steve Jobs who claims that iCloud will gradually wipe out computers from the market.

A few days after the launch of Apple iOS 5.0, Apple introduced the first beta version of the new firmware on June 6, 2011. On June 24, 2011, Apple introduced the second beta version of the new iOS, i.e. iPhone iOS 5.0b2. It seems that Apple was under enormous pressure and couldn’t wait till the final version to fix the loop hole that allowed Gevey SIMs to work and unlock iPhone 4.
