The iFlash USB Drive for your iPhone and iPad.
This thing is so tiny and inexpensive. Forget about paying monthly cloud fees to save your overage of pictures on your iPhone. Anytime you want to view your pics, you just pop it on the end of your phone. Hey, if you accidentally drop your device in the toilet or it ever becomes inheritable… you will still have access to your photos! I looked around and the USB device is a bit pricey at $120.
However, I did find a great price today on MobStub.com at only $22.
