My Keyboard is having this problem. It all of a sudden stops working.. and I have to do a soft reset and SOMETIMES it works... I usually just have to wait til the phone decides it wants to work again. It's very frustrating. Anyway, I took it to Sprint, but unfortunatley, with my luck, it was working when they took a look at it, so they wouldn't help me. Any advice of what to tell them next time? It made me really mad that they just tried it once, it worked, so they said nothing is wrong!
And I DONT wanna wait til the keyboard goes completely out...
