I would like to know if there is anything i'd need to take note if i'm planning to swap a Pre GSM (UK) into a Pre 2 (US GSM). reason is in my place the US GSM does not support 3g..

Q: ANy doctoring of the webos required? / token change?
Q: Do i just turn off the PRe 2 and then swap the comm card, and reboot- or do i need to redoctor with UK doctor?

any help would be appreciated.
