No word yet on what build 7C97D fixes (or breaks). We're hoping not to lose our tether.
Update: Baseband update to 05.08.01 (so if you want to do a SIM unlock in the future, you might want to wait). Also tether and MMS working (mms enabled by default but still issues with AT&T). Startup/Shutdown times dramatically improved, though some people are reporting issues with iTunes playback. Some screenshots also posted to the comments below.
