I have had my Droid X for about 5 weeks. I purchased two after market (Chinese) batteries before my Droid arrived. I have been rotating these batteries from the beginning. No problems. Since the 2.2 update the Droid now says invalid battery and I have a "?" in my battery icon. The batteries still seem to work fine. Just wondering if anyone else has had this issue and is there a way to have the Droid identify these batteries?
