Hey guys,
I think there must be some sort of failed upgrade from this airtell guys.
As from yesterday, it has been hell for me.i couldnt make any calls whatsoever and there network was down.

I have realized that yesterday,from where the network strength bars on my right hand side of the blackberry, it was all 3g  and the bars were only 2 and just a few minutes gone its back to gsm and full bars 5 in number!

Could this be an issue of failed upgrade or what?
