Thank you, both of you for the detail information. I did search a number of discussion groups, and was left very confused, which prompted me to post here. Sorry for posting if it had been already raised before. Unfortunately, I did not learn it during my search online.

Now, I am not tech savvy but pretty good with following instructions - it is clear now that the best option is to go to 001 firmware. I've checked out the video, and plan to update this weekend through phoenix or win flash method. Hopefully, it will all go well. I have been waiting for Nokia to come back, and hoping N9 will be great after spending quite a bit of money on N800 and N810 when they were originally released, and not being satisfied with the experience. Those devices are gathering dust now!.

Thank you again, and have a great day. Cheers.
