i did a restore to 1.1.1 to avoid problems then i update to 1.1.3 using the nates JB method everything seems to works fine, SMS's, calls in, call out, i get sound from the speaker in youtube, when i lock the phone, ipod but i cant get any sound on incoming calls... thx for any help in advance.!

Are you meaning you aren't getting sound from the other side of the call or a ringtone?

If the latter, then I bet's a commonly experienced ringtone issue. You can either downgrade back to 1.1.1 and update/jailbreak 1.1.2 before redoing the 1.1.3 jailbreak (tends to cause fewer problems with 1.1.2 than 1.1.1) or you can install the 'fix' in BigBoss's repository.

It's best to soft update from jailbroken 1.1.2 using either 1.1.3 jailbreak method.
