How to Upgrade 3g Jailbreak iPhone 2.2 to 3.0 firmware?

Iphone 3g crisis:( DESPERATE!! Getting rid of this jailbreak bug?

  • I own an iphone 3g for at&t and decided to upgrade the broadband in order to jailbreak my phone with Cydia. My phone didn't like it one bit and is showing a usb/itunes photograph on screen unable to turn on. When I connect to Itunes (the newest version) It says it is in recovery mode and that I must update and restore it, unfortunately I keep getting error messages. I have downloaded tinyumbrella, ireb, and even a 4.2.1 recovery firmware. Does anyone know how to fix this? Without help I no longer have a phone:(
