Last week Canadian carrier Bell released OS 188.8.131.52 for the BlackBerry Storm to their customers, but it was only really available for download via Desktop Manager upgrade. It's now up on Bell's website, so anybody with a BlackBerry Storm 9530 can now easily download it and give it a go.
Keep in mind that while this is an official release, it's only official from Bell, so treat it with the same sort of respect as you do beta releases if you're on Verizon or Telus (if your carrier isn't supporting the release don't call them expecting support on it and keep in mind certain carrier-specific functions you're used to may not work). That said, I know some many of you are going to give this a go regardless. Be sure to report your findings or jump into the Storm to see what others have said and are saying about 184.108.40.206.
