For those of you that are interested in MMS, you can now enable MMS on AT&T via a simple carrier update. As I stated before, no firmware update is required. This works on 3.0 and 3.0.1. Here are instructions from hacker Gates. Reports from Gates indicate that tethering is still working, although no promises.
If you have 3.1:
- For jailbroken & Non-Jailbroken Phones:
- – Plug in your iPhone, if no prompt, click ‘check for upgrade’
- – Let upgrade happen (it is very fast)
- – Restart your iPhone [DONE!]
If you have 3.0(.1)
- Close iTunes
- – Windows:
- – - Click Start > Run > Type: cmd (and hit enter)
- – - Run this command: “C:\Program Files\iTunes\iTunes.exe” /setPrefInt carrier-testing 1
- – OSX:
- – - Open the Terminal Application
- – - Run this command: defaults write com.apple.iTunes carrier-testing -bool TRUE
- Download the newest AT&T Profile 5.5 (release 9.25.09) [Download Here / Mirror]
- – *Note* This will disable “cellular data network” to keep, see note at bottom (Advanced Only)
- Open iTune
- – Windows – Hold the shift key while clicking update under your iPhone in iTunes.
- – OSX – Hold the alt key while clicking update under your iPhone in iTunes.
- Navigate to the IPCC file (Windows* might need to change file type to IPCC)
- Let upgrade happen (it is very fast)
- Restart your iPhone [DONE!]
**Note** (Advanced Only)
If you use the 5.0 carrier file you can KEEP your “cellular data network” & tethering
In other words-
dtube: Basically 5.5 will give you instant mms with setting configured but will disable cellular data network. With 5.0, you have to configure mms parameter manually, but cellular data network is there thus tethering is
Follow the same directions but instead use this file:

After updating to that file and restarting you must goto “cellular data network” (Settings > General > Network > Cellular Data Network)
And update some your configs
