I've been having problems with my iphone (4s) lately. It will not connect to my wifi anymore, no matter what i do and i have tried everything, restarting my phone, turning it off (my phone and also my internet) reseting network settings, and also restoring my phone and its still the same. i assume that its a hardware problem since my ipod touch 4th gen is connected to the wifi and works also with my laptop but my phone just wont and its bugging me so much. also i forgot to mention that sometimes when i try to go to my wifi settings or cellular data settings on my phone, it will freeze . any tips on what i should do?
