Ugh.. I had to switch back over to my iphone 4, on Verizon. So, I didn't have a wifi connection yet, so going to the app store, it pops up that there isn't any cellular data connection. Says, "Could not activate cellular data network". It shows the 3G icon at the top. I went to Settings > Network and Cellular Data is ON. I've never had that before. I've turned it on airplane mode for a few mins, then turned that off, still no go. I rebooted the phone, no go. I'm lost.
