So I bought a Samsung Captivate this summer for $250. I could have gotten the iPhone 4 for cheaper. Big mistake. The captivate is a buggy piece of crap. If ATT wouldn't hate android so much and I had could get Froyo it would help a lot but alas I can't. Anyways.... I want to buy the 5th iPhone when it comes out, but I'm not due for an upgrade...however...someone told me that with the iPhone you get one opportunity to upgrade to the iPhone whenever you want, is this true? Thanks!!!
