threaded (conversation) email option in wm6.5.x

[Shahriar5252]

Does anyone know how to enable threaded email (Conversation Email option) option in pocket Outlook of Sprint Lovers ROM (CE OS 5.2.28232 (Build 28232.5.3.3)). This is a feature that is available in wm6.5.3. If anyone knows of any ROM or CAB that has this added features for Sprint TP2, please let me know.

I am doing push email using TP2's ActiveSync with my Gmail account. Furthermore, I went to the registry and searched for the word "conversation". There is one DWord that has it, but conversation mode does not appear in my pocket email. Here is the reg key:
[HKCU\Software\Microsoft\ActiveSync]
"ConversationMode"=dword:1

Thanks for your help.
