OH God! My blackberry is nothing but a brick with a pink gel skin right now.
I don't know what to do. I called T-Mobile and didn't tell them that I upgraded to 4.5 but told them I was trying to upgrade to 4.2 and that nothing is working. They gave me some steeps to do but I don't know or think they will work. I'm really scared to wipe out the whole thing like you say because nothing else has worked and just has made my phone even worse. I need A LOT of help.
