I just upgraded yesterday to the I5 from the I4 because of the killer deal at Best Buy. Hand them a working I4, they hand you an I5. Well, I had to pay a few dollars tax, but essentially free. AT&T had been sending me mailers about being eligible to upgrade for $99 to either the I5 or the Galaxy 4S, and I admit I looked hard at the Galaxy because of its screen size. I mostly use the web browsing and apps on my phone; I really don't place that many calls with it. I may well have chosen it over the I5 if I had ended up making the choice in the AT&T store, but the free deal at Best Buy sealed me into an iPhone for the next 2 years. I'll tell you what, the I5 on AT&T LTE network is blazing fast; much, much faster than my I4 was. I can't say I'm disappointed in my choice.
