No firmware issues with the C905 whatsoever.Whatever issues it had has been covered with two firmware updates. Yes, it had a few hardware faults like scratching keypad, but its only in models that are built W44 and behind.All models manufactured W45 hence are perfect.And cummon, you will hear a few issues with it being the largest selling phone this fall in the UK.Not all phones that come out of the manufacturers den are perfect.
