So yesterday I had plugged my Bionic into a stereo to play some music out of it. The phone immediately shut itself off (perhaps the stereo is a transformer?) Ok seriously, though. The bionic then began endlessly rebooting itself, getting to my home screen, notification area says 'preparing sd card', for maybe 3-4 seconds, then rebooting. I took it into the verizon store and they are sending me a new one in the mail. However, I took the old one home and experimented with it. If I take out the 4g card and the sd card, the phone will start up and function fine, albeit quite slowly and obviously with no internet connection. So, if I get my new one in the mail and plug in my cards, will I have the same problem? Is it a phone issue or a card one? I guess my easiest answer is to just wait and find out, but I was curious if anyone around here has any knowledge on the matter.
