I finally got my unlock code from T-Mobile today and put in a "Straight-talk" SIM inside (ATT sim) and the SIM does not have correct APNs (I know that from my previous phone) but when I go to the APN settings its blacked out and I can not edit anything.
Am I missing something here? OS ver 10.1.0.273 .
First time on BB ever, please advise.
