now we all know that MIUI has the voice recording feature but during a call, if you was to record it, it does not record their voice but ONLY yours. (without going loudspeaker) luckily there's already a solution for this problem, skvalex and team. made a program called "Callrecorder" http://forum.xda-developers.com/showpost.php?p=17206970&postcount=635 however it requires your kernel to be patched... I have got in contact with their Developers and here's their reply: "you can ask developers of MIUI to add 2wcr patch to their kernel:http://code.google.com/p/2-way-call-recording/source/browse/#svn%2Fpatches" I've tested this on "Virtuous Unity 2.35.0 Sense 3.0 based on Pyramid" ref: http://forum.xda-developers.com/showthread.php?t=1115312 and it works sweet, but just like many others I prefer MIUI ROM. so I am hoping someone will release 2wcr patch for the miui kernel and share please.
