First of all my S2 stopped receiving MMS (well it received but always failed to download) so I googled all sorts of ways of fixing this, nothing seemed to work. I tripled checked my APN info and was all correct. Called telecom who also confirmed everything was correct and they could said that a factory reset might fix the problem. Have not done that as it is really the last resort. 

However, now my phone is even worse off! Every time I try and install an App the phone restarts itself and the app it not install. It scans for wifi networks but fails to connect even though it recognises and has the passkey saved.

Please help...this is driving me mad.
