OS 188.8.131.52 just made its way onto the interwebs courtesy of our buddy Kevin. This is an update from the 184.108.40.206 that was found previously. This hopefully fixes some of the bugs found in .93. Also developers now finally have the tools to develop for OS 5.0 so maybe this time it will be better?
Hopefully RIM will be releasing a stable build soon since there are a ton of features in OS 5.0 that really can make it worth your while! Let me know how it goes.
NOTE: Do not install this software if you do not know what you are doing. It may make your BlackBerry FUBAR or just plain angry.
