Iphone is the phone which I love most. It has the maximum abiltiy for many business application. It is simply the best. It has so much disadvantage as proportional to its advantage.
It requires a software for your system quicktime player even to insert songs for your iphone, it will not support other company mobiles to share information with your apple iphone. Although it has thousand of applications and it has the maximum sales in other countres. But the another matter for supporting the disadvantages is that it will be go unusable if you just drop from your hand.
