We made some significant 3G progress this week.

Here’s a screenshot of a 3G iPhone whose baseband has been modified.  And even though it’s modified – and fails the integrity check – it’s still running.  Can you guess where the patch was made?

Running modified baseband code is a very useful ability, but it’s still not possible to accurately estimate how close we are to the ultimate goal.

Update: A video of the above session is available here.
