sms is working for me. I don't know about the picture sending part, but text works fine. The lockscreen music player works as well (LeWa Player). I used the newest patch that was provided in the LeWa thread mentioned in the first post, the LeWa_OS_M4_Patch.
The LeWa Player is a GPU and CPU intensive app, so I took tvall's almost_purity ROM and had to use BobZohe's kernel v4 plus CuriousNoob's Gapps.
I added the Calender.
I also changed the host secure file in /system/etc.
It's fast on the scrolling, but a little laggy on opening up apps.
I also downloaded the Theme Zip. I had to take the themes out and move them over to the LeWa folder that was made on the uSD card. I now have 30 themes at my finger tips to choose from.
I have it overclocked to 480MHz min-768MHz max (this also kept the theme chooser app from FC'ing)
It is a little touchy on first boot, I had to just skip sign in (don't have any data connection at this point in the set up anyway) then reboot twice. It then settled right in.
I deleted the DSP Manager and added Beats Audio (had to do this once the ROM had settled in)
It's still kind of picky about what apps you delete or add to the system, so I'm going to leave the useless apps alone until I have found a more suitable Host ROM and kernel.
Could someone explain how to set up a file share site to download the ROM zip from(I am signed up on Dropbox, Box, 4Share, and Google Docs). How to give it a MD5 sum, (basically everything needed to allow other members to download my concoction).
