Samsung Focus On Straight Talk w/ Working MMS
This is a reprint of a working solution I posted on WPCentral.com
Okay, I'm going to try to list the steps to get internet sharing and MMS working with Straight Talk, Please bear with me since I've only been playing with WP7 for a couple of weeks, I'm a webOS refugee and I seek asylum within the Windows world. A couple of props need to be handed out first. To Heathcliff74 at XDA for the terrific WP7 Root Tool and to the wonderful folks at the Windowbreak project for the interop unlock that allows us to do these fine things in Mango. Please note that the WindowBreak only works on Samsung devices. If you have an LG Quantum you can unlock by reg edit without having to do any additional downloads, hacking, etc. Last, but not least, the folks at MS for their Windows Phone SDK 7.1 which allows us to side-load XAP's.
1. Get the Windows Phone SDK 7.1 if you don't already have it. It's a large DL so be patient. The prog you will need to run from here is the "Application Deployment" to side-load the XAP's you will be using.
2. Go to WindowBreak by WindowsPhoneHacker.com ON YOUR DEVICE!! Click on the "windowbreak me" link and follow the instructions. Trust me, it's quick and works perfectly.
3. By now you should have an unlocked device and internet sharing available to you. If MMS is not a big deal to you, quit now and forever hold your peace. If you need it, continue with the sideshow.
4. Fire up Zune and make sure you sync.
5. Now the fun begins, go to the SDK app "Application Deployment and install the WP7 Root Tool from Heathcliff74 from here http://forum.xda-developers.com/atta...4&d=1325517854
6. If you get an error message that your device is pin-locked, go to your phone's app list and hit "interop unlock" because Zune will re-lock your phone at every sync.
7. Now that you have WP7 Root Tools installed, you will notice that you have a file explorer tab. This will become your best friend.
8. Extract the Straight Talk XML from the zip file below and email it to your phone. Tap on the download and save.
9. In the file explorer find the folder called "Application Data> Volatile> Email Attachments> Attachments and find the XML. Cut and paste to the "provxml" folder in the root directory. If the folder is not there, click on the "+" icon at the bottom and create a provxml folder. There should be some XML's already in there that you would have seen when you were doing the windowbreak earlier. Another user told me that he didn't have the provxml folder so I instructed him to find the folders which have these existing XML's. They have names like "Gumi Test Bed, Suwon 2G Test Bed" and so forth.
10. Now go to diagnostic (##634#) and enter *#9908# to get to the GPRS settings. This is the same step you had to do during the windowbreak part of this program except now you will select the "StraightTalk" XML you put in at step 9. Save, reboot and Voila! You should have working data and MMS. Send a test message to another phone and reply with another MMS to make sure you're receiving.
Please note that I've recited these steps from my diminished memory of close to 50 years old and I may have forgotten a step. The most important things to consider are that you have to unlock with windowbreak and you have to get that Straight Talk XML in the proper folder. Once you can get step 10 out of the way you're golden. I won't ask for PayPal donations because others have done the leg work, all I've done is consolidate some files and info and put them together. For that, a simple "Thank You" is all I need. God bless you and God bless our troops overseas.

Just wanted to revise by saying that this same procedure has netted me the same results with a Euro-version Omnia 7. Of note to those who have this wonderful piece of hardware, there are some extra settings that need to be played with for the optimal experience. The Omnia 7 is a tri-band phone for its 3G data. I was pissed beyond belief when I first got the phone and noticed a T-Mobile splash screen and only EDGE speeds. Luckily, there is a key in engineering mode that enables "all WCDMA" and Bam!! I have a beautiful 3G+ icon sitting on my header bar.
After you're in the diagnosis app (##634#) punch in *#2263# to get you to "Test Mode" for band preference. Select option "2" and on the next screen select option "6" for "WCDMA ALL" and exit. That's it! I wish it were more complicated than that.
