I have reserved a 32GB iPhone at a local apple store, the only time they gave me to select was between 2-3pm. I am work from 11:30am to 8pm and the store closes at 7pm on tuesday nights.
Do you think it will be a problem if i go when the store opens at 9:30am to pick up my phone?
It would depend. If there's people ahead of you, then they have made their appointments and they deserve their allotted time. however, if you go in and by fluke no one has made an appointment, then no, I don't see there being a problem. Just make sure if you do get in, that you tell them you had an appointment so they can take you off the appointments so someone else can come in your old allotted time. Just for courtesy, really.
