BB OS question
I have a BB 8800 with ATT and I would like to upgrade to a new OS. Can I us an OS offered by another carrier or do I have to wait until ATT releases their version?
Yes you can use any other OS as long as you delete the vendor.xml file.
See this guide:
You can use any carriers OS that is made for your model blackberry, you will just have an extra step in the upgrade process. Deleting the vendor.xml file before you upgrade.
