Arcsoft MMS 4.0.31.23 & 4.2.8.1 UPDATE! 10-25-07
 

I got it to work. No lie.

UPDATE! I also have the even newer version 4.2.8.1 working too! Check it out in the link under the old one.

Here's my OEM for it.
4.0.31.23:

4.2.8.1:

Unfortunately, I only have the details for Verizon right now, but if some can get me the server address, etc. for Sprint I can update this post with directions for it too.

Now heres the instructions:
1. During BuildOS, choose the new Arcsoft MMS instead of the old one.

2. Once you have cooked and flashed your new ROM, navigate to .[HKEY_LOCAL_MACHINE\Software\Arcsoft\ArcSoft MMS UA\Config\mm1\WspHeader]

3. Add a string value
Name= X-VzW-MDN
Value= your ten digit phone number

4. Change the following value to these:
User-Agent= utstar67kv1
Accept= application/vnd.wap.multipart.related
Accept-Language= en

5. Okay, now open up messaging, hit "Menu", "MMS Options"

6. Select the "Servers" tab, and click "New"

7. Fill in the following:
Server Name= Verizon Wireless
Gateway= (nothing)
Port Number= 80
Server Address= http://mms.vtext.com/servlets/mms
Connect Via= (Verizon Wireless should be here as long as it is set up in your connections, it should be selected already)m

8. Hit "Done", then select you new Verizon Wirelss connection, and hit "Set as default"

Tadaaaaaa! Soft reset, and you should be good to go. This new app will disconnect you after sending/recieving a message and finally uses soft keys. Enjoy!

Yeah, I knew anew one had been released, but I was previously working with this one on the old wm5 kitchens. I figured I almost had it before, lets give it another whack. I'll try out the newest one when I can. Right now I'm just happy this one works.

Whats the name of the ten didgit string you have to create on Sprint?

I don't know. If your referring to the sprint equivalent of the version 9 digit phone number, I don't have that in my registry.

VG - tried to get to the http you listed, but something's not right. Could you take a look? Looks like the raw html is showing up????? Thank you and Phoenx06's for all your work.

This cab will not install on WM6. Has anybody been able to get it to work?

it downloads if you do it using IE or if you do it selecting Save as..

are you getting the pic message on your phone.. or still as a txt?????

and sprint users dont need the 10 digit number as far as I know
