First of all let me say that this has been a great forum for a BB newbie like me. I got my Pearl this week and have been coming back to this site for all the cool things the can be done to the BB.
My AT&T 8100c came with OS 188.8.131.52 and I have been tempting to upgrade it to .164. But before doing that, I want to have my current OS available for backout in case the new version doesn't work out for whatever reason. The problem is, the AT&T site no longer offers .73 for download (they only have .154). So does anyone have a copy of the .73 (AT&T/Cingular) OS?
