If you were to compare BlackBerry Cool to, say, classic television show “Cheers”, I would gladly take the roll of Woody Boyd and all of our regular commenters would be welcomed with a boisterous “YOUR NAME HERE!”. Well, thanks to BBCool regular Keith (KEITH!), we’re pointed to a new OS update from Cingular (version 184.108.40.206) that just might improve your battery life. Keith’s not the only one who’s noticing the difference – anyone else feeling the charge? Let us know.
