This ability we now have to spawn background tasks means we are one step closer to the 3G soft unlock. We have a clear path to follow, and “all” that remains is the implementation.
A quick summary of the key 3G-unlock-related achievements we’ve made so far:
- Unsigned code execution on 3G baseband
- Reverting 01.45 baseband to previous versions
- Patching of static text (the AT&V demo)
- Injection of AT routines (the task list demo)
- Injection of background tasks (this demo)
Now it’s on to overriding the baseband code that enforces the carrier lock.

P.S. That “One more thing!” text is being generated by the backgrounded “steve” task at 5-second intervals. The “A0” is the task’s priority.
P.P.S. Remember…don’t update to official 2.2 when it comes out if you ultimately want a 3G soft unlock!
