Apple fixes App Store bug on iOS 3.1.3 devices, you can hold off on that upgrade

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.
