Good job parasmi!
After I dived in custom ROMs ocean I missed many stock applications (camera with smile detection, SIM toolkit, S memo, S voice, FM radio ... etc) and you reminded me.
There are some bugs I faced:
1. As I am Egyptian, I noticed that Arabic text in any view except WebView replaced spaces with 'ف' letter. And the default keyboard and swype lake to Arabic language. And some of stock applications was translated when I was using stock but here they're not translated.. the last point isn't important for me but it's important for my friends because they don't speak English.
2. The performance of this ROM is a bit good before installing any application (although the RAM is less than 70 MB) and after installing my applications the RAM became less than 40 MB and some games cannot be opened and if opened they lagged. The most dangerous problem that TWlauncher is still restarting and sometimes the phone restarts. I oc'd to 710 MHz.
I wish I could explain my problems, and sorry for my bad English.
