Hello,
I own an iPhone 3gs and am currently running 3.0 firmware. Just wondering about updating to 3.1? If I ever want to jailbreak, can I safely update my iPhone, to 3.1 through iTunes?
 
No I didn't get my ECI iBEC #. Is that all I need and then I can update? Is there a tutorial on how to get those numbers? Is it safe to update to iTunes 9?
 
Do not upgrade until the Dev-Team comes out with tools designed to do so without ruining your chances for a future unlock. If you upgrade to 3.1, you will be unable to downgrade to 3.0, jailbreak (for now), and your baseband will be permanently locked to AT&T.

Definitely true. If you want to jailbreak, unlock or even tether, DO NOT upgrade a 3GS to 3.1.
