Thanks for a great guide! I just unlocked my k800i, and I can now use it with Tele2 instead of 3. One thought, and a question:

* Part I, step 7 should include the same instruction as part III, step 8. The same dialog pops up when applying the first patch. Not a biggie, but it could be helpful for some people.

* I upgraded the firmware when I patch unlocked it. I didn't touch the FS. If I upgrade the FS as well, will that "unbrand" my phone? I got the original icons back when I upgraded the firmware, but the shortcuts are still for "Planet 3" and "3 Player".
