A memory card is your best option.
Most cell phones have a slot for a micro SD memory card. If you know of someone who has one, or you'd prefer to go out and buy one, you should be able to transfer the pictures from your phone to the memory card. From there, you can put the micro SD memory card into an adapter card. It is simply a "jacket" for the micro SD card that allows it to function as a normal-sized SD card. You can then use a computer with a SD memory card slot and put the pictures directly onto your hard drive. Finally, you can take the pictures from your computer, and import them onto your iPod
