Apple Releases iOS 4.0.1 For iPhone
As predictions would have it, this morning Apple released iOS 4.0.1 (8A306) for iPhone 3G, 3GS, and iPhone 4. This is a minor update to firmware 4.0.
Yesterday, Apple released a beta of iOS 4.1 to developers that included many more enhancements but firmware 4.0.1 today addresses only the formula used to determine how many bars of signal to display (you’ll see the difference immediately) on the iPhone 3G/3GS/4.
Below are the updates in firmware 4.0.1:
This update contains bug fixes and improvements, including the following:
â€¢ Improves the formula to determine how many bars of signal strength to display
iOS 4.0.1 is available now in iTunes.
Remember, if your iPhone is jailbroken and/or unlocked or you are thinking about jailbreaking and/or unlocking your iPhone, you should not immediately update to 4.0.1, as you may lose the ability to jailbreak and unlock.
Update: After updating to iOS 4.0.1, I’ve noticed only one thing. Where I used to get 4-5 bars around town, I now get 2-3 bars. Apple has effectively turned my Vancouver-based Rogers iPhone 3GS into a Vancouver-based AT&T iPhone 3GS. My signal now looks worse than usual, everywhere. Apple has perceptually turned all iPhones on 4.0.1 into displaying the signal of AT&T devices. Wonderful.
