I have been asked countless times how to unlock all those slick themes on your BlackBerry. The nice part is that these well designed RIM themes are very good (I personally use the Vodaphone theme on AT&T) and are totally free once you unlock them. Until now there were instructions all over the place but they were not as detailed and thorough as the ones Rcbjr has posted on PinStack.com. Rcbjr calls the instructions straight line and he details step by step with screenshots how to unlock these vendor themes.
Check out the full instructions here on PinStack. Thanks for the great writeup Rcbjr!
NOTE: Rcbjr does not recommend you do this on your nice and shiny 8130 Pearl since there have been conflicting reports on whether it works. Your new 8130 may end up being FUBARed.
