I have purchased an after market USB cord which also charges the phone, i like to use it because than i can keep my home charger at home. anyway i am having trouble with it some times the treo recognized it other times it didnt, this did not happen with any other charger...so i realized my usb aftermarket must be messed up. I am wondering what do you use at your office or connected to your computer, and where is the best place and price to buy it.
