It depends on where you live. I live in San antonio but picked up my phone in Austin. Talked to the rep and he said they been getting a lot of phones in through out the day. They even had a line in the middle of the day outside the store for people buying iPhones that had came in. If you live in a bigger city, it is more likely you will get a iPhone soon since they get bigger shipments
Which store in Austin? They've all shown unavailable for me today. I'm in San Antonio. I visited the one in North Star yesterday.
Yesterday even though my rep swore they had them, they most certainly didn't. Waited a few hours like the guy asked and no go. I talked to like 3 people. One said they'd had them and to wait, another said they'd been out of them since morning and the third I'd tried to buy a 5s from. They weren't able to do any T-Mobile jump upgrades the whole day the third guy told me. So nothing....
All in all, it was just a ridiculous experience.
