Earlier this week, we looked at a way that some iPhone 4S users were able to get early access to the beta release of iOS 5.0.1 through the AppleSeed program. At the time, we were expecting it to still be at least another week until Apple finished its testing and was ready to release the final version of 5.0.1 to its users. Instead, now just over a week since the beta first went out to developers, 5.0.1 is going live for everyone to install.
The big change in 5.0.1 is the inclusion of some patches that should hopefully fix the problems that iPhone 4S users in particular were having with their phones discharging their batteries too rapidly. There are also some bugfixes included for iCloud services, and better dictation support.
When the beta first dropped, we noted that it included unspecified security fixes. We now understand those to be related to the unsigned code exploit we recently talked about. There has been some talk of using that exploit for jailbreaking the 4S, or making current jailbreaks untethered, so iOS hacker MuscleNerd warns not to upgrade to 5.0.1 if you’d like to keep that hole open, at least until a means to downgrade is discovered.
You can update to iOS 5.0.1 now through iTunes, or directly from your phone with the new OTA update feature.
