Well, it looks like Apple hasn't completely left behind older iPhones and iPod touches stuck on iOS 3.1.3 just yet. After a few days of not being able to download or buy apps directly on the devices due to a recent App Store update that rendered such basic features unusable
, Apple has now returned things back to working order. We've confirmed that ourselves on a first-generation iPod touch running 3.1.3, as have a number of iPhone and iPod touch users on the official Apple support forums. As with the bug in the first place, there's no actual software update involved here -- everything should be back to normal as soon as you open the App Store on your device.
