As we are on the HK900 thread i can shed a few tips for anyone interested, China mobiles as they are called are usually hacked to hell and non compatible with the official Nokia update in any way and they usually come with heaps of apps on them so my guess is once they do get there hands on the N900 officially for sure it will follow the same trend and be non updatable from Nokia direct as they will have as usual their own update sites which are always in Chinese.
They always copy everything and one of the good sides is heaps of cheap spares can be got from them and as the years have gone by i must admit the quality has definitly improved a lot.
I was thinking ... ok get a China product code but they wont be available on the net yet for obvious reasons and then try do an update from Nokia but nothing on Nokia site yet even if you did get the product code for a N900.
I also think Nokia will sell only a limited amount to China as they will start to produce thir own copies and not get from Nokia.
Just a bit of info if anyone is interested.
