I'm about to send my N900 in for repair. I bought this phone in May/June 2010 after a few months the AC adapter was no longer working, as of yesterday the usb to microusb connector is no longer charging phone either. My Car AC adapter used to charge the phone as well. That no longer works. I have tried other cables both ac/usb2microusb, and none seem to work. I notice the microusb connector on the phone looks crooked. Most likely I will be shipping it off today. Hopefully Nokia will notice the problem and fix and or replace/refund it. I will update everyone on the status with returning this phone to the USA care center.
