Heya. What has your experience been with third party cables, and in particular, has anyone used digipower cables? A friend of mine says she bought one and it wrecked her battery. (it was an MGear cable). I'm looking at DIGIPOWER FIRE WIRE CABLE IW-01 and I want to make sure it is compatible with the new iPod touches, (Yes.. I realize that the prong is firewire..) and that it won't wreck my batt. Can anyone chime in on which off brand cords to avoid and which ones are okay?
