Hello, I just got a iPhone 4s from ebay unlocked. I installed my T-mobile sim and we are off !!! Problem that i ran into is when i try to setup the wifi the wheel spins but it never finds a network. I know my network is ok cause my ipad air and MBP connect just fine, So just to be sure I reboot the network, Nothing I reset the network settings, also nothing.. Someone told me that I mite have to open it and replace the antenna but before I order a new antenna i wanted to see what you guys think. Thank you for reading my thread.
