rigacci, what I found is BackBeatSuicide has the link in his post. In my search I found another link that has he update split into two files. The one I used is in a single file. The configuration requirements are thesame for both. So there are two options, I wasn't sure how the second half was going to install so I opted for the single file. If your phone is rooted or at a different version than .330 then you have to follow the instructions for rooting the D2G . If your Droid is stock and .330 firmware follow the directions from the first pos That' where the file link is anyway.
The two files were (at least originally) for different purposes. One was the straight update (at the time .606) for stock UNROOTED .330 phones. The two parter was a pre-rooted version of .606 for those that wanted root under GB. This required bootstrapper as the files cannot both be called update.zip!
This came up just before the D3 rooting method, so now there is no real need for a prerooted version.
