btw, i'm currently using SPB 3.5, after much tinkering, i think this is a much superior shell then Samsung...not to mentioned way faster too! Heck, now i don't even bother about WinMo 6.5...
I've downloaded the VITO Chat...seriously, this is how SMS should be, not that clunky horrible WinMo SMS editor, which Samsung TouchWiz UI is based on. SMS threading, easy fowarding, multiple recipient etc are added easily. My wife will love this.

I almost regret buying this phone coz she keeps complaining so many user unfriendliness issues...
So far this is what my wife has complained and how i resolve it....life is tough for the husband who has to do technical support for the wife!!!

1) No direct way of creating NEW SMS - default Samsung interface goes into WinMo with clunkiness that requires like 3 steps to create new SMS.
Solution: Create a shortcut link to the TMAIL.EXE(with parameters) and dump it into the \Windows\Menu folder.
2) Sorting of contacts by Last Name, then First Name...

I wonder who remember people by their surname first...
Solution: Use a software called 'Contact Changer v13'. (Thanks to the guys here!)
3) Cannot foward SMS!!!
Solution: The option is hidden in the Reply->Foward menu option in WinMo SMS...really stupid design. Solved by VITA SMS. So easy to use!
With SPB 3.5, the usability is so much better, but i miss something from Samsung widget though. Can i get those widget to run in SPB 3.5? Like Yahoo FInance...this is very useful to keep the fav stock code in the list.
Any ideas??
