Worth upgrading to iOS 4.1? (3GS)

[boo__]

Hey everyone,

I've got a jailbroken/unlocked 3GS on iOS 4.0 right now, and I was wondering whether it'd be worth it to upgrade to 4.1. (Correct me if I'm wrong, but going to 4.2 isn't possible if I want to keep my unlock.) I know that I'd have to use a custom firmware with an older, unlockable baseband, but is there any reason to upgrade to 4.1? Has Apple included any useful fixes or anything worthwhile? I checked wikipedia (iOS version history - Wikipedia, the free encyclopedia) but most of the fixes apply just to iPhone 4 or 3G.

Thanks for your help!
