Photos: Cracking open the iPhone 
Published: 06 Jul 2007 12:46 BST
Unlike most other mobile phones, the iPhone's case can't be opened in order to replace the battery or access the SIM card. The SIM card is held by a small holder in the top of the iPhone.
To remove the SIM card, insert a paper clip or other thin, round tool into the small hole on top of the iPhone. Then push it in to pop out the SIM card holder and card.
