might seem a daft question but i'm going to ask anyway. i am on o2 and debranded my phone when it was on 1.6 so i could update to 2.1 now that o2 have released the 2.1 update i was thinking that it could be wise to flash back to 1.6 rebrand my phone to o2 and then update it again back to 2.1 although this is a little time consuming more than anything else, i know its not a hard task. but is there a way to rebrand the 2.1 to o2 without this hassle? mainly thinking this could be a wise thing to do for the warranty if ever needed (again). i am rooted so if its a simple code change (as it was with 1.6) then i can do that easily enough i see at the very bottom of the default.prop file ro.semc.version.sw=1227-4612 ro.semc.version.sw_revision=2.0.A.0.504 ro.semc.version.sw_varient=GENERIC ro.semc.version.sw_type=user i assume i can maybe change that to the o2 codes? my old code was 1234-4762 so changing the first line seems to make sense but unsure if it is that simple.
