Verizon iPhones left out of update
As expected, Apple has released iOS 4.3.1, a minor firmware update for its handheld devices. The patch appears to be aimed strictly at bugfixes, for instance correcting graphics glitches on the iPod touch that were spawned by iOS 4.3. It similarly copes with flickering on some TVs when using the Apple Digital AV adapter.
The firmware also deals with a problem in enterprise web service authentication, and several bugs that affected activating and connecting to cellular networks. The update can be downloaded through iTunes, and supports the iPhone 4 and 3GS, the iPad 1 and 2, and the third- and fourth-generation iPod touch. The iPhone 4 update is limited to GSM models however, leaving Verizon customers on v4.2.6.
