ive had the HTC desire Z for around a year now and ive had no major problems with it untill recently.
My little sister decied to mess with the security pattern and guessed it wrong too many times. i was required to enter my google account info but was not connected to the internet or wifi at the time so i had to format my phone. I entered the settings required for 3's mobile data, and it seemed to work fine for a while but then started to turn off by itself after only a few seconds of activation. i turn on my mobile network and its off again in 5 seconds...
yet wifi works fine with no disconnection. any help with this??
