Expected to quash bugs, undo jailbreaks
iOS 4.3.1 is already in the works, and it should be ready for the public in as little as one to two weeks, a report claims. The release is said to be a minor one, fixing issues such as a problem with Springboard and/or third-party apps failing to detect the gyroscope on the iPad 2. Also in the firing line are memory corruption when reading large files in the USIM filesystem, and a glitch with NTLM authentication in apps and on websites.
Jailbreaks are another target, with Apple specifically undoing the ability to jailbreak the iPad 2. Likely sabotaging some earlier hacks is a baseband update for the iPhone 3GS and the iPad 1. Whereas firmware can be rolled back relatively easily, baseband updates cannot be undone and often break methods used to jailbreak and unlock iOS devices.
Still unknown is whether or not iOS 4.3.1 will apply to the Verizon (CDMA) iPhone. Support for the device was, for reasons unknown, explicitly excluded iOS 4.3. The phone is however running iOS 4.2.6, which already includes some of v4.3's features, such as personal hotspots.
