I have noticed the following bug after updating to PR1.1:

After placing a call using Skype or SIP I can't redial again using the original method (Skype or SIP even though their icons are present) from inside the call log. If I initiate a redial the call can only placed via regular cellular line and not Skype or SIP. I have to go into contacts and choose call type in order to use VOIP line!
This wasn't an issue before the latest update.
