The udpate is available for the GSM iPhone 4, but no update has been made for the CDMA iPhone 4. That device is still on iOS version 4.2.6, released in January.
The iOS 4.3.1 update is also available for the iPhone 3GS, iPad 2, iPad and the third- and fourth-generation iPod touch. According to Apple, the update includes:
- Fixes an occasional graphics glitch on iPod touch (4th generation)
- Resolves bugs related to activating and connecting to some cellular networks
- Fixes image flicker when using Apple Digital AV Adapter with some TVs
- Resolves an issue authenticating with some enterprise web services
This week, it was rumored that Apple would issue iOS 4.3.1 within two weeks, making Friday's release somewhat unexpected. The accompanying notes make no mention of battery issues reported by some users of iOS 4.3, nor does it say whether a security hole exposed at a recent hacker conference has been patched.
News of iOS 4.3.1 came earlier this month via the Pwn2Own hacking contest, when security researcher Charlie Miller revealed that Apple has a fix in the works for a flaw in its Safari mobile Web browser. Miller exposed the flaw at the contest, and privately shared the exploit with Apple to help the company patch its software.
Also Friday, Apple released Xcode 4.0.1, also a minor update. Changes to the software, according to Apple, include:
- Improved Assistant editor logic when switching among different file types
- Fixed a bug in "Install Xcode.app" that hangs at 99% complete, never finishing
- Fixed a bug that prevented indexing of some projects
- Fixed a bug related to nil settings in the Core Data model editor
- Fixed a bug that prevented automatic download of iOS documentation
- Fixed a bug in LLVM GCC 4.2 and LLVM compiler 2.0 for iOS projects
- Additional bug fixes and stability improvements

Whatever. not updating
Cool. Updating now.
As for battery issues with iOS 4.3, I found the advice to turn off Ping service, and my iPhone 4 seems better for last several days:

I've been having wifi issues on my 3GS, with nothing else changing but the upgrade to 4.3 on multiple wifi networks.
Its like the 3gs doesn't see wifi networks (or doesn't see more than one in a multi wifi network environment), and then maybe it will see one briefly, then maybe it'll connect or maybe it won't, then once it is connected its a weak signal (2 bars max) even if its in the same room as the router (usually Airport Extremes or my Time Capsule, but any wifi network really). Then after a while the connection will cease to work, but still shows as connected, so I have to switch off the wifi. This is while my mbp is connected and works fine the whole time. Frustrating. Everything else is constant in all these locations and has worked flawlessly for over a year.
Can't wait to get home and see if this gets fixed, I sure hope its not the hardware, because that would suck.
Fixes an occasional graphics glitch on iPod touch (4th generation)
Does that mean it will fix the notification graphics glitch (blinky boxes and distortion)? I have to wait till I get home to try it out.
