hi everyone! i'm planning to buy a used ipod touch 5th gen, the seller says the unit is in great condition however just don't have it restored or updated. i wonder why is that so? i'd mainly use it for music and taking pictures/videos and a little bit of browsing the internet. will i have problems if i'm not able to have it restored or updated? i mean i'm fine with iOS 7, could i just leave it as it is?
