Hi all, I have an problem with iphone t-mobile. My status bar disappearing and when I locked it then it appears again and this process is going on from last 3 days. Besides that my phone is not giving any signal now though the t-mobile bars were reflecting there but I was not able to make any calls and I was not able to send any message also. I have my iPhone (3g, V.3.0) unlocked with ultrasn0w.So, can some one tell me why is this happening and how can I fix it.
