I am using my Neo (latest Qtopia image) since about 10 days as my primary business phone. I am a quality engineer of automobile industry and the main problems I have before deeper testing, is that the Neo will not establish a bluetooth connection with the handsfree system of common automobile bluetooth units (OEM). Further more I haven't found a seperate charger for the Neo. I charge it at home with my Linux-machine and during work the battery get's flat after about 4 hours using it. My windows-business-machine won't load the battery, which means I have to wait until the next day. Is there somebody out there, who can give me an advice which wall-plug-charger I have to buy and secondly which car-charger I have to buy?
