Well I have been an iPhone user for years. Decided a couple of months ago to sell my iPhone 4 and give Android a try. I purchased the Samsung galaxy s2. At first I was very happy due to the larger screen and thin factor. However that quickly wore off since Android was just too let's say finicky for me. Also the battery life was absolutely terrible! I aw only able to take it for 2 months so I sold the Samsung and am now a happy owner of iPhone 4s. So far I have no issues, in fact I have almost stopped using my iPad 2 all together (may sell very soon) a I can't put the iPhone down. Didn't realize how much I missed it.
