Hi there
Icemanmods.
I have the same phone you have. HTC Touch Diamond with 6.5 windows. I have it running on Mightyrom 6. Almost everything was working since a soft reset after install. The only tweaks I did to the phone were to install a few apps to get the auto screen rotation (Flip_It by Wilberry Team), Resco Explorer, A_C S2U2 screen lock, and Arcsoft MMS_5_2_6_45U for the media mail. Unfortunately I haven't been able to send Picture or Video. I do however receive Picture and Video.
Internet works like a charm with excellent speed, WiFi kicks a.ss, haven't tried WMNWifi Router though (I will tested later now that I think about it
).
Like I said, pretty much everything worked from the get go. So Im thinking its your Wm 6.1 thats causing some setbacks for you. But I can relate to you. For the past 3 weeks I've been going nuts searching everywhere for a MMS Arcsoft that will give me Full MMS in & out or a tweak or system editing to make it happen. If I find something I will hit you up.
Not sure if this is the route you would want to take. Just my 2 cents.
