Recently (last night) hooked an unlocked Tmobile 3G onto the Wind mobile network in Canada. Was using it fine late last night and early this morning, downloaded a couple of apps and was using the keytag app. Put the phone down to have a shower and when I returned the phone was dead. Will not power on, LED is not lit when plugged into charger or USB port. Tried soft reset (battery out) and hard reset (home and back button) but still nothing. I was very happy and ready to play all day today, anyone have some hints and help?
