1. Re-flash the stock sprint rom, radio and everthing. Let customizations run.
2. Once the handset has rebooted, open internet explorer to connect to the internet.
3. Open your dialer
4. Goto Menu -> Options
5. Click on "Services tab"
6. Select "internet" and click "get settings"
7. Make sure you are connected....Step #2
8. Click "start" and let IOTA run
9. Now you can flash whatever rom you want...

Give that a try...
