See this thread at XDA. There has been a Gingerbread ROM released for the Venue. It is for Region 14 (Korea, Olleh KT network). Hopefully there will also be a release for the region 00 phones (retail), which are the ones purchased from Dell unlocked.
Edit: It seems that there is a major problem with this ROM - DO NOT USE. Read the thread linked above for info.
