Sending my L920 for ATT warranty

[ricbon]

So I am sending my L920 for warranty with att the dust in the FFC got out of control. The only thing is I have GDR3 installed is this something i should worry about it going back??

Trust me, ATT rep will not even know you have gdr3, they will just give u a 'new' like device. I exchanged my Lumia 920 which got bricked trying to flash under warranty. They don't bother to check for these stuffs as they are not well trained about it
