So yesterday, my phone froze for no real reason, so I took out the battery and put it back in, but when I tried to turn it on, and after I entered my password it still said "phone off", so I tried to turn it on again, but it kept freezing up and just said "network search" up at the top and there was this weird little symbol with a red T and I couldn't get it to work. So I backed it all up on my computer, did a hard reset, and put everything back on the phone, and it worked for about two hours, but then it stopped working again and I can't even get the hard reset to work. Someone help me? Please?
