Really a awesom product. I am from last 2 years now. no complaints of any kind. only issue is battery life but that is also not such a big issue.
Actually I am using 32 gb memory card really cool. camera clarity call reception everything is really good on this. this phone was dream of steve jobs and he has really made a piece of art. his sudden death was a real set back for apple. apple could not launch anything like I phone.
