Hello there guys!
I got a 3GS iPhone with the new bootloaders, i had jailbreaked the 3.1.3 using Sprint Jailbreak Tool.
Then when iOS 4 came out i updated it normaly but every since when im plugging my iPhone into my computer i am getting a message saying to update my carrier settings. Thus i have NO 3G internet which i should had...so my broadband internet is not working cuz of that carrier thing

Any ideas guys?
