For those of you who have been watching the iPhone threads, I have been trying hard to get the MMS working, but I couldn't get it to work.
I just want to warn everyone that: group texting will not work if you don't get mms fully working and tethering may be an additional charge, as it shows up differently in your bill.
If you want to reverse anything you have done, you'll need to fully restore the phone by:
1) If you entered any terminal commands, you will need to make that command be "FALSE" instead of "TRUE".
2) Clicking restore
3) Restore as a NEW iPhone -- This is important, as the carrier file will be changed for a new one, the 4.0 version.
This is a pain in the ass to wait for the sync, but it is the most effective way.
Anyone who says to "call AT&T" to set up MMS is either a liar or a lucky individual, because I have tried 5 times and had no luck everytime (a supervisor tells them that MMS is available "later this summer).
Have fun.
Actually, my hack (on krillr.com) can be reversed simply by downloading and reinstalling the IPCC from http://appldnld.apple.com.edgesuite...erBundles/061-4732.20090203.gj3ef/ATT_US.ipcc
No restore needed.
