I got mine from Phones 4 U
The manager strolled up to the store at 8am and said she couldn't beleive people were waiting for the iphone.....all 4 of us.
Round the corner at the o2 store there were more than 100 people in the queue.
Me and my mate had put a deposit on ours so we were served first, all the systems were incredibly slow, it finally went through but the networks were advising up to 24 hours for all sim swaps to be processed, it was done by the time I'd got home though as my old iPhone had gone off.
Whilst we were in there a lad who worked at carphone warehouse was in there, he said it's a sackable offense to buy one of the stores stock, so I'm guessing this retailer in question is from there, the staff at the P4U store couldn't have been more different, they said they're expected to buy their phones from the company they work for!
Whilst we were in there the manager from the O2 store came in as they'd only had 40 phones delivered and were asking if it was OK to send them down....naturally they said yes!
