Ever since I got my 3GS all I wanted in an upgrade was a bigger screen! Then the 4 came out with the same screen size so I didn't upgrade. Then the 4S came but still the same screen size. Iphone5, finally a bigger screen so I was excited to finally upgrade. All I can say is WOW! I love this thing! It's a huge upgrade from the 3GS, Not only I got a bigger screen but all the other great stuff and Siri, Come on Siri is the bomb! Anyway I know most people only post on the forums when they have a problem with their phone so you dont really ever see and read about all the non-problems and how much we love this phone. I have no problems with my new At&t phone it works like a charm and it just went into the new otterbox defender which is great! So if you still have a 3gs you should upgrade it's a huge upgrade for us!
