Yeah… With latest Tytung r9 beta kernel, you can record phone call conversation now (2-way in call recording). Currently, there are 3 NAND Android ROMs that I tried which is using Tytung r9 beta kernel. And I managed to record my calls with BOYPPC-SHIFTPDA GINGER HoneyComB. Besides Tytung r9 beta kernel, all you need is a call recorder application by XDA Developer, skvalex.

Okay, I am back to HTC HD2′s world. Some complaint about absence of HTC HD2′s posts. No worry, HTC HD2 is still alive and kicking with Android 2.2 Froyo build and future Windows Phone 7 build. Can’t wait to have triple boots.

Zevele’s AutoLoudspeaker had been updated to v1.4 from v1.2 and got some useful add-ons like below and fixed some bugs…
Tired to turn on loudspeaker manually by yourself? Here is an Windows Mobile application created by Zevele called AutoLoudspeaker. It will automatically turn on the loudspeaker when the phone is away from the ear, and turns it off when it is near the ear. Loudspeaker will automatically switch on if the proximity sensor is unblocked and off if it is blocked. Isn’t it nice?
