I wanted to let you know that the team has released a system update for the Xbox 360 over Xbox LIVE.
Sometime over the next few hours when you sign in to Xbox LIVE you’ll receive a prompt to accept this mandatory update. If you are signed into LIVE already, you may be signed out and asked to accept the update and you’ll be back online in a few moments.
There are no new features or changes in this update. This update is preparation for additional system enhancements (Facebook/Twitter/Last.FM) that will arrive later this year.
Again, there are no new features in this update.

Note: Of course, just like the previous update this will update the first stage bootloader if needed and thus make the JTAG/SMC-Hack impossible. You have to stay pre-849x if you want to run this hack.
For DVD FW modders … update at own risk as always
