for the past 2 days i haven't been able to access the net via 3g. i don't know if it's the ipad2 or the sim card.... but both have been working well prior to that. i am attaching an image... it shows the carrier window under settings... it is set to automatic (it keeps searching for the carrier), but on the left panel, the carrier name has already been identified. i checked with my carrier, they said that data access is still active. can anyone help? my ipad2 is JB. thanks!
