My phone carrier is tmobile. I recently bought an iPhone 4 n unlocked it with a gevey ultra. The version is 4.3.5 and the modern firmware is 4.10.01 and I had my tmobile sim for more than 4 years. I notice my signal would fluctuate to 1-4 bars and searching for signal. So, I got a new sim and now my number in the phone setting shows unknown. I tried to typed my number in manually, but it will not save. Therefore, I cannot receive any mms and the message will pop up please go to your phone setting and type in number. Any advice?
