Hi, I had an iPod touch 4th Gen the white one with iOS 5 and I've had a wifi issue, I would notice that I would lose connection on the iPod (on safari and other apps that require internet) but the wifi icon would still be up there.. The only fix was to turn wifi on then turn it back on.. It happened twice or three times in 2 weeks so I returned it and bought another 4th Gen from eBay the black one with iOS 4.2.1 and i just had the same problem today after having it for almost a week. My connection is fine I was using the internet fine on my computer when the issues occurred plus both iPods were running different iOS... So am I the only one who had an issue like this? Or am I just unlucky and bought faulty devices twice?
