GUIDE: Another way to install data, MMS, and tethering settings to your iPhone
Alright, here is my setup guide. It should give SIM swappers a better option than the mobileconfig solution in the first post of the thread:
-This will override any AT&T carrier bundle installed on your iPhone, including the default one. If you use other at&t SIMs (including from MVNOs such as Locus, Consumer Cellular, H20, Jolt, or AirVoice) and/or other modified at&t carrier bundles, this method may not help you and you should follow the mobileconfig instructions in this topic's first post to retain data access.
-This guide assumes you are on iOS 4.0 to 4.2.1. If you are not, it might be a good idea to update to 4.0 or above (if you need to retain a carrier unlock, go to blog.iphone-dev.org and grab pwnagetool). You should also remove the mobileconfig file from the topic's first post if you had been using it (go to Settings--->General--->Profile and remove the config file).
1) Go to the following site, download the linked file and follow the instructions in the zip file: http://www.hackint0sh.org/f127/191761.htm
This will allow your iPhone to accept unofficial carrier files (including the one I'm posting here).
2) Download the following file, unzip it (be careful Safari users, it may try to unzip the file twice), and place the .ipcc file someplace you can find later:
3) If you have iTunes open, quit iTunes. Then, depending on the OS, do the following:
a) Mac: Go into Terminal and put in the following:
b) Win: Go into Command Prompt and put in the following:
defaults write com.apple.iTunes carrier-testing -bool YES
4) With the ST SIM in your iPhone, plug it into your computer and startup iTunes
"%ProgramFiles%\iTunes\iTunes.exe" /setPrefInt carrier-testing 1
5) Once iTunes starts and you can get to your iPhone's summary tab: shift-click (WIN) or option-click (MAC) the "Update" or "Check for Updates" button. A popup window should appear.
6) Find the folder you put the .ipcc file you downloaded in step 2 and double click the .ipcc file. iTunes should then popup saying 'Updating Carrier Settings" or similar. Once that is done, you should be good to go.
7) (Optional, but recommended) Restart/Power cycle your iPhone.
8) To check to see if it worked, go into Settings--->General--->About and look for Carrier. Carrier should say 'Straight Talk 10.0' if it installed correctly.
-You should be able to enable FaceTime, as its settings are in the file. YMMV if it allows FT activation on your device.
-MMS, tethering, and data all work. It may take some time for tethering to show/start up.
-This file should allow you to modify the APN settings (Settings--->General--->Network--->Cellular Data Network) if you need to change them for later use. IMO, the APN settings shouldn't be tinkered with once you install this file.
-This should allow you to manually select a network (Settings--->Carrier) when needed. The setting doesn't always show up and may require you to restart your phone or remove/swap SIMs to reenable it.
-I don't know if there is a CommCenter patch for the iPad. If there is such a patch, then you can also use the ipcc file here to make your SIM work well on a jailbroken iPad. If not, then the mobileconfig method on post one of this topic should work for your needs.
-The carrier name in the status bar will read the following when the following 'networks' are in use:
HOME: Straight Talk
--HOME is the default name for at&t's AND T-Mobile's network on ST SIMs, so don't be alarmed if you're not getting 3G when it says "Straight Talk" as you may either have disabled 3G (Settings--->General--->Network), in an AT&T area without 3G (parts of the midwest, for example) or you are on the T-Mobile network. You can find out what network you're on by going into field test mode (Pull up phone dialer, type *3001#12345#* and Tap Call) or by installing the Signal app in Cydia.
