Jacob let me know that US Cellular has officially released OS 18.104.22.168 for the 8830. This includes both ESN and MEID devices so nobody is left out in the cold. Not sure what is new but this is the latest release since Sprint released .135 in February.
Let us know what you find in the new OS versions in the comments below. Keep the tips coming!
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.
