I had this problem starting from last night. After I took the phone out of airplane mode, it would not go into 4g at all. I tried rebooting and updating the PRL with no luck. Fast forward to this morning, I turned airplane mode back on and when i turned it off, walla! I was able to connect to 3g again. Now at about 5 something today, Im suffering the same problem again! It is stuck only in 2g. I tried updating the prl and also tried turning air plane mode off and on again and this time it diidnt work. How do I get my phone back into 3g?
