Finally, XDA Developer, pongster updated his build ~ HyperDroid CM7 to v2.1.0 which is based on latest CyanogenMod 7 Android 2.3.4 Gingerbread and using latest Tytung R10 Kernel. As usual, it supports Google Talk v1.3 which has video and voice chat functions.
By the way, I changed it LCD density to 240 because I don’t like the default 167 density. Make sure that you change ro.sf.lcd_density=167 to 240 at build.prop (system folder) before you install the ROM if you want normal screen density.
