We have mentioned CrackMem a few times on BerryReview and I just wanted to explain why. CrackMem is a simple application by Pete at CrackBerry that gives you a GUI to edit the installation of a new OS for your BlackBerry with ease. Instead of opening up .alx files and editing them or deleting Java .cod files you can just click a check box.
This means that deleting the vendor.alx file to install another vendors OS now only takes one checkbox in CrackMem. The latest version 3.1 adds the ability to remove Google, Facebook, Flickr, VZW Navigator, & ICQ
You can read more and pick it up in the CrackBerry forums at this link.
Nice work Pete!
