Lg modified their kernel which is probably why they're still on 2.x

The 4XHD can record phonecalls so it definitly has a 'modified' kernel. In this case it's modified by LG themselves to provide for this and maybe other functionality that we aren't even aware off. LG has to patch the new kernel with the same functionality as the 2.x.x kernel first before releasing it to the general public.
Which is probably a reason not to have the latest 3.x-kernel.
Just try it. Call someone, while still in the call go to the apps-menu, start voicerecorder and it'll start recording the call (with a 10 sec beep). The HTC One X can't do this, nor can the xperia U nor can the galaxy S III nor the Galaxy mini (which i tried too this afternoon). Most phones can't even operate the voicerecorder while in a call.
This alone is a unique feature which LG should advertise as a major selling point. I can't understand why they don't.
Nonetheless, I hope the call recording tip is of use.
