http://stejskalservices.com/ROM/SPB-12-25.7z for SPB MS 3.5.2 (final size 115,959 kB).
The biggest updates are a couple extra SIPS (Phone Pad, HTC keyboards), a registry editor, and a few misc. changes. Oh and SPB was updated to 3.5.2. Nothing else is new and if you cab installed the new SPB you aren't missing much.
