I tried to set it up last night in the apple store after buying it, but got that dreaded AT@T will email you when its ready message. Well, around 11 I got an email saying my current plan wont work with the iPhone. Thats fine, I say. So I call AT@T and get it sorted out, and am told it should only be a few minutes now before it kicked on. 40 minutes later, nothing, so I call back. A lady now tells me it may take even up to an hour. Its 1 am at this point, so I say screw I'm going to bed and surely it will be up and running come the morning.
I wake up and see that my current phone now has a "Unregistered SIM". Good news I thought, progress. But alas, the iPhone still does not work. Connected to iTunes, it says it takes additional time to activate. Aye. So I call again. This time, it may take up to 24-36 hours to activate. I'm certainly not happy, and now I have no cell phone. wtf.
