iOS 4.3.1 is available for the GSM iPhone 4, iPhone 3GS, iPad 2, iPad, and the third- and fourth-generation iPod touch. No update is available for the CDMA iPhone running on Verizon.
Earlier this week, a report surfaced claiming that iOS 4.3.1 would be released with 1-2 weeks, and a follow-up report had suggested that the release might address some battery life issues reported with iOS 4.3, although that has yet to be confirmed.
