IPhone SDK 4 background process for incoming call
I would like to track (run some code - or invoke function) when the user get an incoming call. 
for example: for every call the user receive I want to save the number, and check something during or before the call is answered (with a background process..)

until now without the background processing I couldn't find a way to do this. But I'm still not sure it is possible.

I'll be grate full if anyone with information about the new sdk 4 or a good idea to solve it can help me please.

Thanks. Shai.
