This is what I've found with my Chinese 3650...
Get it in 4 days.
Get 16mb MMC card.
Early beta OS
Crashes quite often
WAP browsing only 16 colours?
No 'photo fun pack' software.
3rd Party applications often cause 'green screen of death'
To me the cons are not a problem for me as it means having my phone early - I just hopt that Nokia will upgrade the OS for me when the official english OS is released.
If your in the UK then it looks like the release date will be March 15.
So can you wait that long or are you willing to put up with the short falls of the chinese one.
Oh - and off course - you'll pay thru the nose for an import...
If I were to buy again - I'd wait.... oh - and it's well worth the wait
Fantastic phone - you you WILL get used to the dodgy keypad..
If only there was a 'slide' on the back cover which protects the lens, then it'll be perfect.
