Hello friends! I am using iphone 4 from last 4 years and even today I feel like its brand new. There is no problem with battery life. There is no hanging problem. It has been fallen many times but there is no damage to the phone or no scraches. It is very handy phone and have compact size. It has 5 megapixel primary camera and result is quite good. Its front camera has low quality. And it has 3.5 inch screen, inspite of that is a great phone.
