Apple today has released iOS 4.0.1 in a bid to fix the reception issue which has been plaguing iPhone 4 users since its launch last month. This new update addresses the reception issue which is experienced when the phone is tightly griped in the left hand.
Note: Except for iPhone 4, all iPhone jailbreakers and unlockers are highly recommended to stay away from this release. This release may contain new baseband which might not work with ultrasn0w 0.93. If you rely on an unlock and update to this firmware now, you will lose your unlock for God knows how long. You have been warned!
