So i got it last month when i upgraded from a blackberry. Today, i plugged it in to my computer to put my itunes music on it and i worked fine but now every time i tried to turn it off, it turned back on. Then i found out that all my contacts got lost so i logged back into facebook and it didnt help. None of my apps (including antivirus) will stay open for more than a few seconds then it will say it cant run and ill have to force close. Also, none of my widgets can load. Whats wrong and what should i do?
