The iphone is fantastic mobile phone. It can connect you up to the internet very quickley. It has a large touchscreen which replaces the buttons. It only comes on one network in the uk which is O2. It will cost you £250 for the phone then an extra £50 per month for the contract. It comes in black. The Iphone has lots of usefull features. It has a built in 8gb memory space. There are no butons on it only the touchscreen. If you want to buy one then i think you should got to the apple website to find out more information i've never owned an Apple product so i can't tell you a lot about them.
There is also an iphone 3G which is half the price according to apples website. You've got things like the internet, calender, mp3,maps, whether and of course a phone. The new iphone 3G costs £99 in the uk a lot more than what the other model is. You can use the phone to control Itunes. The iphone looks like the old one the same touchscreen and some of the features. It is still only on O2 in the uk. If you try to change it it may damage the phone and it's software.
