I was digging through my closet and found my old iPod 5G. The battery is basically shot and the hard drive seems like it's on its last legs (lots of arm clicking and restarting) but the device itself is in great shape. I was thinking about replacing the battery and upgrading to a flash storage solution. Looking around though, there are many kits that either use the older compact flash cards or the newer SDHC sticks. Which kit is most recommended by you guys? Any info would be greatly appreciated.
