I've seen several folks trying to get their hands on mobile SDK 0.8.2 to work on older Titanium projects and having mixed results tracking it down.
Here you go, mobile SDK 0.8.2:
Just unzip it into Macintosh HD > Library > Application Support > Titanium > mobilesdk and restart Titanium Developer. When it launches again it should see the SDK.
Hope that helps someone!
Thank you! I have been looking for this all day.
