how to update an unlocked iphone's firmware?

[SPNarwhal]

my iphone has version 2.2.1 on it right now,
i heard that if you update it just by updating that it will break your iphone.
so, how can i update it to the newest firmware while keeping it unlocked / jailbroken?

would i have to reset the iphone completely and delete everything and then re-unlock and jailbreak it?

haha

owned by a Newbie ya gotta love that! it's a 3G or lower. Since the 3GS never had 2.2.1 so it easy to do but I think op should do a little searching!

it's a 2g.

2g is simple just update to official 3.1.3 version. then jailbreak and unlock again

Yep, just update to the latest 3.1.3 and use redsnow to JB and unlock.

I really tried, but after more than 20 hours, I couldn't resist !

Break as in melt or explode in your ear ?

Or just cease to function ? Sorry just too funny to pass on !
