There are few more bugs in DEFY Epsylon3 16/04/2012.
1.WIFI hot spot doesn't work. It works for the first time and turning off will not work, so we have to restart.
Replacing tiwlan_drv.ko helps to fixes the bug of switching off but WIFI hot spot doesn't work after replacing.
2.USB tethering doesn't work too. When i hit connect. It connect but disconnects within 3 seconds and next time when i hit connect,it displays as if connected but nothing works.
