Great job keep testing with low/no signal area to normal signal also wifi on and do some heavy usage.
Fingers crossed
It works really well wifi till now had no problems i downladed every Gameloft game works great, also even with low signal strengh i could send and receive sms without problems i send and receive about 40sms without problems did some phonecalls (about 10) never lost a signal, had wifi on about 3 hours. After the update till now after some heavy usage my battery droped over 10 hours from 75% to 30%. So i hope that it is fixed.
