Is there anyway to manually update the carrier file?
Here's the link that tells you how to get itunes ready: http://modmyi.com/forums/t/565871-guide-mms-t ethering-working-t-3-0-iphone.html
Here's the download for carrier settings 5.5 (what was released on the 25th): http://www.quickpwn.com/wp-content/uploads/20 09/09/att-us-ipcc.jpg
Save that image as "ATT_US.ipcc" (no quotes obviously) and load it to your iphone using the instructions from the first link.
