I have an Iphone 4 and today I installed the updated Iphone Software over the air using a WiFi connection. After it was all done, my phone shutdown. When I turned it back on, I got the "Plug into Itunes" message. The only problem is I'm traveling abroad with only a tablet (Asus Transformer) and I have no way to plug into Itunes! What can I do to use my phone again! Help!
