Using an Iphone is like using any other Idevice like iPod Ipad or even a regular phone the only thing different is that
1. you can jailbreak it for free and its Legal to get free apps
2. it got apps for help or entertainment
to use it when downloading apps off the app store it will pop up on another screen to get to that screen you slide your finger from right to left getting to the other screen
also you can have an iPod in it
the sleep button is at the top right to close and open it the middle is the home button to exit apps but if you have
( Ipod 4G, iPhone 3GS, and iPhone 4) you double tap the home button to multitask without exiting your app and going to the home screen and looking for the other app
under settings you can turn wifi on and off
also you can take photos on the left off the phone are two buttons and a swtich the frist thing is the buttons are for volume and the switch is like a mute vibration. That's almost all i got
