okay i have firmware version 5A347 on my iPod that i got from the XML file early on July 11th. Im getting told so many different things... Which firmware version is the official one? When i say official i mean the final build. the one there selling. not that dev build that they say slows down your iPod and can wipe the HDD. it would make sense that the "official" one would be 5A347 because 7 is after 5 (i think)? but i just wanna know so i can have the "official" one on my iPod. also i bought apps and such on the app store. if i were to restore to a different firmware would all the apps still work for my iPod?
