Mine 3G's backlight isnt working, and I am afraid I may need to send it in to Apple. The only problem is that I have been testing the betas of 3.0 on it resulting in a 4.26.08 BB. Is my warrantee still valid?

Where are you from? Im from New York / Long Island Area and I have already gotten 2 replacement iPhone 3G 8GB from Apple from Long Island Apple Store (Roosevelt Field) and One from Westchester Area (West Nyack) never had a problem....I dropped my phone lol and it was scratched and it was bugging **** out of me so I called Apple I didn't tell Apple on phone that yea I got 3.0 because they don't support that yet but I said Im running latest version 2.2.1 phone is freezing my battery lasts like 1hr and all they made me appointment went to Apple Store and they said ooo you got 3.0 how you like it blah blah blah and they replaced it anyways so in my opinion I never had problem I guess it depends where you go and on person I dealed with the managers in both locations...Hope this helpss

When you do the downgrade to 2.2.1 you can try to downgrade the baseband: Baseband Downgrader

I have heard of a lot of people that have gotten refused warranty service from running 3.0. But everyone I heard was running 3.0 when they entered the Apple store. I have not heard of someone who was running 2.2.1 and Apple checked the baseband and refused service. Good luck!

Ive had a few replacements and not once has the genius actually checked my baseband....

Ya they usually wont check the baseband......but if they notice 3.0, you will be refused.
