I am planning to buy an iphone and am all set to buy it but one of my friend suggested me that Samsung captivate is also a good phone. But I know about these only that iPhone4 comes pre-installed with Apple’s new iOS 4 and Samsung saptivate is powered by Android 2.1. so can any provide me detailed comparison like samsung captivate vs iphone 4. If someone has any idea or know about it please tell me also ……I would really appreciate …..thanks a lot
