I successfully used the qdl tool to get 2.2 on my locked Streak. I plan, however, on using the official release when it comes in. When Dell/AT&T finally releases 2.2 for the Streak will I be able to update or do I have to downgrade back to 1.6 first? If I have to downgrade back to 1.6 will a simple "Restore to factory" do it or is the process more involved? Also, is there any point (i.e. will the released version be exactly the same)?
