    SIM cards never hold much more than contacts, and on an iPhone I don't think this is even the case.

    Change the sim from what phone? Why are you changing sim?

    I think Im calling the card by the wrong name. For some reason SIM came into my head. Im talking about the card that you take out when you use the paper clip to open at the top of the iPhone.

    Thnx and sorry :)

    sim cards don't hold that kind of information. they mainly hold your carrier information (account/phone number/etc). the iphone's only holds that which i think is lame. every other GSM phone you can store your contacts on it (makes switching phones easier) and some (like SE) allow you to store sms/mms/email messages on it as well.

    so no, your ringtones and whatnot won't transfer. but they're on your computer/itunes library so why would you need them to? you just transfer them onto the new phone when you sync it.

    You have the right name.

    The SIM card's primary purpose is to supply customer account information to the wireless network.

    If you take the SIM card out of the iPhone and put it in any other phone, your price plan, telephone number, etc all travel with the SIM card into the other phone.

    None of your multimedia (ringtones, pics, etc) are usually stored on your SIM card.

    It is also possible to store a contact list (names, phone numbers, etc) on a SIM card, but I don't know if the iPhone uses that capability.

    SIM = Subscriber Identity Module

    It identifies you to your network the local cell tower communicates wiht your phone and registers your IMEI and SIm and that is how calls come through every time you move into a new area your IMEI is logged by the provider.

    No data is stored on the SIM on the iphone except the SIM serial number which is tied to a phone number by your service provider

    Also the SIM card can't hold much information. On my old Razr I couldn't store voice prompts. Even if the iPhone could I wouldn't think that you could put pics or ringtones on it.

    Right and the new iPhones will have a SIM built in again... Anyway... if you have previous version of the iPhone your numbers pics and other stuff is backed up in iTunes. They will be transfered when you plug your phone into iTunes the first time...

    that's because razr's couldnt do a lot of things. you can actually store about 64kb worth of information on a sim card (at least ATT/Cingular's 64k cards). that would normally entail your contacts, but you can also store messages like i mentioned above. you can't store ringtones, games, etc on it though.
