can anyone verify this fixing any radio problems ?
ive had 4.0.4 IMM30B for a while but everytime i go from wifi to 3g it stays grey until i manually turn off data then turn it back on. this is also the case 70% of the time after a phone call. it would be nice for my phone to resume data after wifi is turned off or after a call ends without have to do that EVERYTIME ... other than that.. my nexus rocks
But what is happening to you is extreme and should not be going on. You may be better off just taking your device in and trying to get a replacement unless you would like to try this first.
