I had my Droid for about a month now and love it. My girlfriend loves it too so I got her one. After I did a hard reset of phone and went to update to 2.1 via OTA I noticed the file size was about 69 MB. I had the signed-voles-ESE81-from-ESD56.fa406da6.zip file on my computer and saw that it was about 16 MB, extracted it was about 22 MB. Is there a difference between the OTA file and the manual update file? I would rather flash to 2.01 and then upgrade from memory card and then root but was wondering why the OTA download was so much larger... Thanks!
