Give it another try...
Jailbreak witj limera1n
1.visit www.limera1n.com and download tiny strong software for Jailbreak.Follow the instructions on software while on run.
2.Backup all the files and photos on iTune before doing this.
3.After Jailbreak your phone will return to the normal state but without a carrier and you might not have the network, Dont worry at all.
4.Connect to WiFi and start your phone.
5.Tap Limera on Home Screen or second page.
6.The List will Load the application "Cydia".
7.Tap on the link and install Cydia.
8.After Installation phone will get restarted.
9.After Restart find Cydia application on screen and open it.
10.It will load the repositories and run. Go to search and find for ultrasn0w.
11.Go to untrasn0w once you find and install the package.
12.Phone will restart in "All you need mode"
13.That all. Now if its work for you ... I will be the most happiest cuz i spend whole 10 hrs in R&D with my Locked and screwed up iphone in 2010 sometime ago.
Cheers and Take care of your iPhone.

Perhaps check APN settings. Typically AT&T plans wouldn't require editing the APN but that may help if set.
Does the SIM work for calls without ultrasn0w?

If its showing "No Service". Try seraching network manually and select.
Also for 3G and data network ask your operator for APN settings or refer to any other iphone setting which is working.
