I need help getting MMS on samsung Instinct flash to metro pcs I look on Instinct Forum and found nothing
found this instructions on howardforums
1: Install Arcsoft MMS version 5.0.70.24 from Verzion. Too big to post here and I'm a bit nervous about the whole 7 day ban thing so you'll have to find it on your own. Google for "GC VZW Arcsoft MMS 5.0.70.24" and you should find it for download.

2: Open your Messaging and click on the SMS/MMS option.

3: Click on "Menu" and select "MMS Options" then select the "Servers" tab.

4: Add a new server with the following settings:

Server Name: metropcs
Gateway: wap.metropcs.net
Port number: 3128
Server address: http://mms.metropcs.net:3128/mmsc
Connect via: SELECT EITHER THE CONNECTION YOU SETUP ABOVE OR "The internet"
Send limit: 399K

5: Click "Done" and then set the new server as default.

6: Using a Registry Editor edit the following values:

[HKEY_LOCAL_MACHINE\SOFTWARE\Arcsoft\ArcSoft MMS UA\Config\mm1\WspHeader]

DELETE KEY -> "X-VzW-MDN"
ADD STRING -> "X-metropcs-MDN"="XXXXXXXXXX" ( Insert your 10 digit phone Number )
ADD STRING -> "X-DEVICE-MIN"="1XXXXXXXXXX" ( Insert your 10 digit phone Number WITH the 1 in front of it )
But I need to know how to use a Registry Editor Help Please!!!

Here is a link to "GC VZW Arcsoft MMS 5.0.70.24" link is not mine
