I have been having a tremendous amount of problems with my 8120 pear freezing. T-Mobile tech support couldn't figure out the problem, and sent a replacement phone, and the new phone had the same problems. I finally figured out it was the SD Card causing the problems. The problems started when I updated my device software to the latest version. I had a 4G card in it for a long time without a hitch, I bought an 8G card, and didn't have any problems either for several weeks until the software upgrade. Now my phone freezes with the 4G or 8G card, I even bought a new 8G card thinking that was the problem. Any way to downgrade to 4.3 software? Any fixes?
