Wow, I'm a dummy. I was stuck in Airplane mode all last night, frustrated, rebooting, then today I just remembered, "hey, didn't I post something in the forum with this exact question"? So I Googled "ppcgeeks.com whiteblazer01 stuck in airplane mode" (so I can bring up my post), and I read the 2nd post (which solved my problem last time), and DUH! I am using a new replacement T2 I just got yesterday - and it had a SIM card in it!! SIM card out, and problem solved. Whadda dummy!! LOL
PS, for those stuck in Airplane mode without a SIM card, I don't have an answer.
