This has the markers for a horrible day.
Since the weekend I can send/receive on my 8120 when it's in wifi, but I can only send messages, that is to say I can't receive messages - this includes PIN, messenger, email and net - when it's on EDGE (I'm on Rogers)
No, it's not OS specific, I've tried several (including the leaked 4.5) and yes, I've tried popping the battery, cycling each wireless connection off and on.
Anybody have any ideas? I'm going koo koo for coco puffs over here
