how do I download pictures from my old sims card?

As far as I know, pictures don't get stored to SIM cards. Are you sure you don't mean an SD card? If you're talking about an SD card, you can use an SD card reader to move the pictures from your SD card to your computer and then sync from there.

There are two problems here: SIM cards don't support storing of images, and iPhones don't use SIM cards for storage. If you mean an SD card, then you need to synch with a computer or use a camera connection kit.

You don't.

What pics are on your SIM card?

Iphone does not store to the SIM card.

You can import contacts from a SIM card ( if youor old phone stored to SIM).
