Important Newz!!!
Guys as you may know apple as release the new beta firmware 3.1. This firmware will be release soon!. If you guys have your iphone 3g or 3gs jailbroken/unlock and want to keep it on that stage don't upgrade to the new firmware 3.1 because it closes the hole used by the dev team to jailbreak and unlock the iphone. Always wait for the Dev Team tools before upgrading your device if you want them jailbroken and unlock. :)
