my contract with sprint ends this Oct and I plan to move to ATT. I am with sprint from day one and don't know anything about ATT. my company has 17% discount with ATT. I have a few questioms: what is the best way to set up plan and order iphone? through ATT coporate discount site? Is it better to buy iphone from Apple or ATT? if Apple is better, how do I set up plan with apple and use corp discount? if I find the service is not good at my house, within how many days can I cancel acct and return phone? if this happends, what happened to my numbers? (since sprint accout is already closes due to porting) I plan to get the cheapest family plan with one iphone and one dump phone. with sprint I got 550 min with 6PM NW, ATT NW is 9PM but has rollover. I hope this rollover will help out a bit for the 6PM loss. any other advices that I might not know about?
