Where did the SIP settings go to on my LG Optimus 4X? About 3 months ago I bought my LG Optimus 4X HD (aka P-880), which shipped with Android 4.0.3. I searched the settings up and down, and was quite surprised there were no SIP settings available. I'm very sure SIP support was added to AOSP with Gingerbread, so it had to be there with ICS!

Did LG remove them from their Android installation? Is there any way to get them back?
That sip settings are hidden in "activities" below "Telefon", it took me a while to find it. Creating a SIP Account was possible but it was not stored permanently. After closing the sip settings and opening it again it's gone. Still using Vimtura Vimphone as sip dialer.
