After my iPhone died I was given a new 32G G3S for my birthday. It was hacked. I did not like the blackra1n. My calls were endlessly dropped, no emails function. I thought I could go back to factory settings. All I get is a message saying SIM not support. I bought a new SIM, no luck. Can't go back either way, been told to throw it away. Any hope? Or should I use it for target practice?
