I was looking at a soldering pick set for $4 instead of $8 and maybe a 6 foot long iPhone usb cable for $2 that will be used for charging only, not syncing.
Pretty low-tech stuff.
I discovered a long time ago to have the ability to charge cell phones anywhere, anytime, without plugging, moving, returning, or otherwise jacking around with cables. So every car, computer, travel bag, computer case, and a 6 foot so can be wall plugged and usable at the same time. I obviously use my phone for business, and am mobile, not in an office all day.
