Does an iPhone have a charger?

No not many of them do. But what you do get with most iPod touches is a cable to plug into your computer and you can charge it from there. If you want you can buy a mains charger in the shops for around £20. But be careful because all three 8gb, 16gb and the 32gb need a different charger. To charge the ipod touch up completely it will take around 6hrs.
