just add your apn again or use the IPCC file again never rest your network

Having updated to beta 5.0 and using itunes 8.210b, you cannot add/install the carrier settings file.

Also, in the phone settings, the section showing the APN entry and the like is not visibile.

How come yours is visible ? What versions are you using ?

The documentation says to call Apple support, which I did, but they hadn't gotten it fixed for a couple of days, so I decided to ask AT&T to switch my data plan to the iPhone (I was on Blackberry Enterprise because I switch between the two) and it worked. Not sure if it applies to you, though.

OK, my problem solved.

I tried MANY different options. The last option worked (of course).

1. Removed latest version of iTunes. I believe it is 8.2b10
This version does not allow the updating of carrier file (.ipcc)
1a. Installed iTunes 8.2b7
2. Restored iPhone to 3.0 beta 5
3. Tested phone, Data Access did not work
4. Hooked up phone to itunes again
5. Did Shift-Update
Selected file ATT_US.icc (attached)
6. Clicked on Open
7. Settings updated
8. Rebooted phone (Power - Home until white apple on screen)
9. Went to Network settings and setup the right APN for AT&T
APN: wap.cingular
Username: WAP@CINGULARGPRS.COM
Password: CINGULAR1

Viola !! Works like a charm. There is even tethering option. Not tested yet, bu appears for selection to enable.

Good luck.

I have the same problem, I've fixed eveything but the the 'No Data Network' error. There is no place to change APN settings. Can you please tell me what you did?

[bchandler78]

Google APN Changer! It's a web site that you visit with mobile safari that will allow you to make a new profile.

Best of luck!

That's what I was looking for! Your the man! I knew you could set a fake APN but that must be new? Thanks!!!
