You may have noticed - WinterBoard wasn't working on the iPhone 3GS.

Well guess what? It is now.

The newly released 0.9.2958 versions of MobileSubstrate and WinterBoard (upgraded to support ARM7/Thumb2) should now work on the iPhone 3GS.

Open up Cydia, and download away... everything is working spot on
