I just got one off Ebay for $10 with free shipping after seeing this post over at XDA confirming it fits with the stock door of the CDMA Hero. Also further comforting my skepticism: this post from a G1 owner with an Andida extended battery from the same ebay vendor who had nothing but good things to say after testing. Ebay link: http://shop.ebay.com/350304192720 Anyone here try this one out yet? I will be reporting back within a week or so with my results. I just tossed the Gumbo kernel + SetCPU on top of Fresh 1.1 and am LOVING it so far. Running "on demand" mode for now which maxes out at 528mhz when awake and turns it back to 160mhz when sleeping.
