Well I hadn't had any data issues until this morning. :-( I did reboot my phone last night because Board Express Pro went all kinds of crazy. (I have a love/hate relationship with that app). But I was on WiFi last night. When I left the house and went to use TellMe for a text message, it told me I didn't have data. Rebooted, but still nothing. Airplane mode, reboot. Still nothing. Plugged in the APN information figuring I just got hit with the issue and will now patiently await the update.
At first when Nokia said it was a memory mismanagement issue I was scratching my head a bit, but when Board Express did what it did, it made a bit more sense. I wonder if anyone who did 'all of a sudden' start having issues had anything similar happen just before they lost data.
Regardless, a fix is coming. Data is 'patched' at the moment, and I'm getting $100 credit...so...I'll rest knowing it'll be fixed soon.
