Even though I am by no means a luddite, I still used my 3G until a week ago, when I upgraded to the iPhone 5. What a world of difference! I am still impressed by how fast everything is compared to the 3G; it's life changing really. Even though my wife has a 4, I decided not to upgrade to that and held out for the 5. I was very disappointed when the 4S debuted last year and decided to wait yet another year for LTE. Very glad I did. My old 3G, still in great condition because I used a case the entire time I had it (except for its last week of use, when I rocked it naked), will now occupy a space on my shelf next to my old Razr, LG, and Samsung flip phones, and the Nokia that was my first cell phone.
