On Friday I left work early, went to the Apple store in the Burlington Mall in Burlington, MA. I was worried when I saw the length of line, but Apple reps were assuring us they had more than enough phones. After a 3 hour wait I got my 16Gb white iPhone, brought it home and played with it the rest of the night: I absolutely LOVE it so far! (I had a Helio Ocean before this.)
After seeing it, my spouse wanted one too, so we set out Saturday morning to go back to the same Apple store, and on the way we decided to stop at the AT&T store on Winter street in Waltham just for the heck of it. It turns out they had ONE 16gb white left and he got it! So, after a 0 minute wait it took us 10 minutes to do the purchase, convert my account to a family plan, activate the phone, and leave the store. So far he's loving his phone too.
Good luck to everyone still trying to get theirs!
