Got it working, yay!

Hey,

Wow, who knew WM6.1 would create such mess eh?

Well I went through some searching during school today and found the tutorial for setting up Arcsoft MMS with the MMS resender!

http://xdaforums.com/showthread.php?t=288136

I followed every direction, except I didn't download the MMSResenderv1.1. I did more searching and found version 1.2 (which I placed in the Startup folder) and it works perfectly with my TyTn!

*****************************************************************************

Now what has to be done?

(Credit to Kilihari for his awesome tutorial!)

Alright, first you have to setup the MMS connection. Go to Start -> Settings -> Connections Tab -> and tap on the Connections icon.

Then, under the My Work Network, click 'Add a New Modem Connection'. Give a name for your connection (ie, Softbank MMS) and select the modem: 'Cellular Line (GPRS, 3G). Tap Next.

In the access point name field type: mailwebservice.vodafone.ne.jp . Tap next.

For the username put: vodafonelive , and for the password use qceffknarlurqgbl . (double check to make sure it's typed correctly!)

After, tap finish. From there, you'll see your newly added connection. Click the General Tab and under where it says 'Enter a name for these settings' type VFJP Network, then tap OK.

(Note I'm not sure if this is necessary, but in the tutorial forum, one person mentioned doing this ensured it working.)

Alright, now that you have the connection setup, the Arcsoft MMS has to be configured for use!

Return to the Today Screen and open up Messaging. Tap Menu, then go to Tools -> Options...

It will display your installed accounts, tap on MMS.

Now, in the MMS settings page tap on the 'Servers' Tab.

Tap New.

Under Server Name type: mailwebservice.vodafone.n (it doesn't allow more characters, this will be explained later and solved with a little registry tweaking).

Under Gateway type: vfkkmmsproxy.vodafone.ne.jp. Then for the Port Number use: 8080

In the Server Address type: http://mms/ and Connect via VFJP Network, or whatever network you used to add the Softbank MMS connection earlier.

Set the sending size limitation to 300K and the WAP Version to WAP 2.0. After, tap Ok.

Tap and hold on the newly created configuration and set as default. After, delete the Sample configuration and Tap Ok.

Alright now to tweak the registry. Make sure to end all tasks using the task manager (Start -> Settings -> System Tab -> Task Manager)

Fire up your favourite registry editor (I used PHM Regedit). And navigate to: HKEY_LOCAL_MACHINE -> SOFTWARE -> ARCSOFT -> ArcSoft MMS UA ->Config -> mm1.

First lets change that server name. From 'mm1' navigate to MMSCSetting then to mailwebservice.vodafone.n.

Find the String called 'Name' and make sure it says mailwebservice.vodafone.ne.jp .

Alright, after, go back to mm1 and navigate to WspHeader.

Under the User-Agent type: Vodafone/1.0/V802SE/SEJ002 and tap ok.

Now suspend the device by pressing the power button. Wait 10 seconds then resume it. After, close the registry editor.

Finally all the MMS Settings are now set, but we aren't home free just yet, the system still needs the MMSResender program (attached below). Download the ZIP file, and transfer it to your device. Open up File Explorer and locate where you copied the MMSResender.exe. Copy it. Navigate to /Windows/Startup and paste it in there.

Close down File Explorer and Soft-Reset your device.

After a reboot, try opening Messaging and sending an email using MMS. If all done correctly you should see a 'Message Sent' notification.

Congrats!

Again thanks to Kilihari for the tutorial!
