Any way to change this / remove / transfer the branding version on a 9100? The replacement phone I bought recently is technically "unlocked" and is the specific model phone that I was looking for. However, due to the "branding version" the phone only allows traffic on bands 1, 4, and 8. If I want to use it on my current provider (AT&T) I need a different branding version for bands 1, 2, 5, and 6/19). I have two old 9100s that I have been using for parts which have a branding version for Vodaphone-UK and one for Cingular. Both have the firmware imprint for those bands. I tried "switch devices" in the BB Desktop software which doesn't transfer that little gem and haven't been able to find a way to do it in BBSAK either. Am I missing something obvious? Please help? Thanks!
