So.... I'm with Verizon and am planning to get an iPhone 4. I priced out the 3GS and they required a $150 deposit. Not bad but whatever. My question is this: Do the security deposits differ from what the Apple site says to what AT&T will ask for? $150 isn't that bad for me. I just dont want to go into AT&T and they're like "Oh, BTW, we meant $500 and your soul as a security deposit." Has anyone had anexperience where the deposit differs in-store versus online? P.S. Also, do security deposits differ by iPhone model, i.e. $150 for a 3GS, >$150 for an iPhone 4? Or, is it all SSN based? Thanks in advance.
