iPhone 4S: Lag during phonecalls after updating to 5.0.1

[xxfrozenrayxx]

I have an unmodified iPhone 4S running on the H2O network. After I updated to 5.0.1 I noticed that there is a strange lag during my phone calls. It takes about four seconds after pressing Call for the call to start and two-three seconds for the call to end after pressing End. Also when I have to dial a number while talking to an automated service the number doesn't register for one-two seconds after pressing it.

I've tried restoring the phone but it still does it. The problem isn't that terrible but it is very annoying knowing I didn't have this while I was running 5.0. Anyone else experiencing this?

Having same problem, i’m on Tele2. I’m also experiencing strange lag while using Apple supplied earbuds with mic. Calls lag and jitter, music too.
