Damn, I had to use this hack for three times :
  • First time when I found update, there was not enough space on my phone
  • Second time there was not enough space on my HDD
  • Third time I've got it right
BTW, I have HTC Mozart and what worked for me:
  1. Change MobileOperator string
  2. Wait 26 seconds
  3. Disable data connection
  4. Wait 5 seconds
  5. Drop VPN connection

I've attached modified (uses 000-88 instead of empty string) ChevronWP7.Ringtones.xap file for HTC. You can use it with original tutorial.

Oh, and thank you guys for all those helpful posts
