OS 188.8.131.523 for the BlackBerry Storm2 has been leaked and is available online. The download links for these leaked OS posts go down fast so download now and make your decision if you want to install later.
Brent over at Simple Mobile Review did a post on Shrink-OS which allows you to remove components of the OS install you won’t use to free up additional memory making your Blackberry perform faster and giving more room for you apps. Memory isn’t as huge issue on the Storm2 like it is the original Storm, but, it does go quickly so give Shrink-OS a go if you currently are short on memory on your Storm2.
