I wipe cache, dalvik, factory reset and system twice every time I flash a new ROM. I updated to LK8 using Sextape and Garwynn's update. I flashed Perseus kernel in the same session with the ROM. Using Handcent with stock messaging frozen, I haven't had any issues with SMS or MMS (my usual setup). I haven't figured out how to get weather on lock screen through multiple reboots, and playing with the settings, but that isn't really an issue for me. Being unable to use dialer codes to set multimedia proxies and ports to 0 is an issue, biggest reason is YouTube doesn't work on Wifi (connection to server lost). Dialer codes usually only work on unthemed dialers, or if the multimedia proxies are set to 0 inside the ROM itself (from previous phones). Everything running super smooth, great battery life so far and I haven't had any force closes.
