Dunno if this has been asked, did a search and didn't find anything. I'm buying the iPhone 3G, but I'm wondering what all has to be charged to a card. Is it just the phone itself? The reason I ask is because I don't use credit cards and the only plastic I have is a debit card. ATT said they take debits, but I have a limit. So what I'm wanting to do is pay for just the phone on the debit card, then pay the rest with a check. Will this work? Thanks!
