The service of HP in USA is excellent. I screw my 2210 when I update the Traditional Chinese Rom to English one. I sent my PDA on Wed by UPS and have it back on Friday (w/ English Rom).
I just sent an email on Sunday regarding the just the 2210 side grips. And I got a package of 2 side grips, 1 battery cover, and 1 CF cover on Tue.
The best thing is, I didn't pay anything for above.
