Ipad2 cellular data service problem with I0S 5

[franki]

After upgrading my IPAD2 from IOS 4.3.3 to IOS 5, it is showing a message "Could not activate cellular data network...you are not subscribed to a cellular data service" even if there full bar globe 3GS signal is indicated and cellular data APN setting is correct. Globe cannot seem to figure out what the problem is. Anyone who has the same problem and solution?
Thank you.

You probably solved this by now but FWIW, I discovered that the upgrade changed the APN setting in my ipad to Globe's postpaid APN when it should have been using the prepaid APN. After changing that back, I didn't have any problems.
