hey guys, i just bought the N900 4 days ago, regardless the reboot issue. i woke up yesterday it rebooted and it was it, it stuck and don't want to continue loading. even when using the closing button its not working. i removed the battery and reinstalled it again and tried to open the N900, but the same thing happened, loading ........... then stuck. Please help me what to do. is that a hardware or a software problem, and how to slove it, or do i return the phone?
