Sorry for brevity - on ipad. Traveling for work, iPhone on att has been working 100% fine. Suddenly, I pull out phone 20 minutes after updating Facebook and it says the phone needs to be activated. Confused, I try via cell network. No dice. Get to hotel, try wifi - same error -says actuvation servers can't be reached and try again later. Phone is completely unusable. Tried a off/on, a reset, and taking out sim, blowing, and putting it back in. Can't really do much but keep trying as I'm working and there's no apple store near. Can't com home for couple days and need the phone. Any suggestions? Thank you! EDIT: oh, just so it's clear, I'm in USA and am traveling within the states. I'm in WI right now.
