Now we're working in iTunes:
3. In iTunes, click on your iPhone on the left, and control-click on "Check for Update"
4. It'll open up a window to navigate to the "ATT_US.ipcc" file that I attached.
5. Reboot your iPhone
6. Go to Settings -> General -> Network -> Cellular Data Network.
7. Scroll down to MMS
8. Type these into the correct fields:
Code:
APN: wap.cingular
Username: [email protected]
Password: CINGULAR1
MMSC: mmsc.cingular.com
MMS Proxy: 66.209.11.32
MMS Max Message Size: [leave blank]
MMS UA Prof URL: [leave blank]
9. Reboot iPhone
10. Go to Apple - iTunes - Download iTunes and get the newest iTunes
11. Install that, quit iTunes, and move the iTunes folder back to ~/Music/ and replace the old version, and now you have tethering and MMS =]
To use tethering:
1. Go to Settings -> General -> Network ->Internet Tethering
2. Flip the switch to on, and select which mode you wish, either through the cable, or over bluetooth. The cable is the easiest since it charges simultaneously.
Doing the process sans another phone (experimental):
Complete steps 1 thru 9 from the "MMS and tethering enabling" section. If MMS should fail, which it probably will, continue with these steps:
"1. On your iPhone go to Settings>General>Network>Cellular Data Network and use these settings for MMS
Code:
APN: wap.cingular
Username: [email protected]
Password: CINGULAR1
MMSC: mmsc.cingular.com
MMS Proxy: 66.209.11.32
MMS Max Message Size: [leave blank]
MMS UA Prof URL: [leave blank]
2. Try sending a MMS, it should fail. Once it fails reboot your phone.
3. Now go into Settings>General>Network>Cellular Data Network and the username and password that you just entered before the reboot, should be blank. Leave them blank.
4. RE-APPLY the same ATT_US.ipcc file to your phone, with the previous instructions above.
5. You should be ready to go."
