I recently bought this wall charger for supposedly the iPhone 1G, around there: [www.monoprice.com] It says "compatible with 1G iPhone", but when I started to use it with my 1G iPod touch, it started to behave erratically. It DID charge up the battery to a usable state (around 10%), but it doesn't go any higher over the course of 2 hours. In addition, it behaves strangely in Safari in that it "vibrates" the page even as I'm not moving my finger on the screen (my finger is on the screen but not moving). I thought these iPod chargers were universal? What do you suggest I do?
