I asked a question about booting into recovery mode here and tagged it with "t-mobile G1" because that's the device that was giving me grief and because I suspected that the phone manufacturer and model might be relevant to the answer. Looking at the answers, it does seem to be relevant: "Apparently download and recovery modes are merged for the G1."
Al Everett went through the other night and pulled the "t-mobile g1" tag off of most of my posts. In most cases I understand -- ultimately the questions and answers weren't G1 specific (though I didn't know that when I asked them). In this case the answer was so I'm curious about the logic behind pulling the tag. Thanks!
