As always it seems different phones give different results. Why, I have no clue. The ONLY thing I did to get MMS working on my Sprint phone was Flash R5, chose Sprint on the provisioning screen, rebooted. Then did registry change renaming SMS to SMS.htc and that's it. All the SMS.htc does is show the WM MMS/SMS screen in your inbox. I edited NO servers etc. My CDMA Servers tab has nothing in it. But yet I can send and receive, tested multiple times with my son. Don't know why some have issues. Hopefully ya figure it out.

You won't be able to send via the HTC Messenger you will still have to goto the Mail tab, tap inbox, slide to the SMS/MMS box and you can tap Menu and New and select Picture message. You can also goto album and select the picture from there select send via mail and select Picture message there as well.

I did not install any other Arcsoft, the new one Juicy included worked for me.

Good Luck.
