I played with my new Dell Streak for five days while running Dell's stock US Android 1.6 build. As I said five days ago my goal for today is to load the Dell O2 Android 1.6 build and then upgrade it to Android 2.1
I took my time so I could document my steps, but due to several wrong turns, it took me about 4 hours to piece together the fragmented information from several blogs. My Dell Streak is now running a clean non AT&T build of Android 2.1 on the AT&T network. I'm very happy with it and would do it again.
I will post my notes and clean them up as needed as I find things that need to be changed.
