With all the fuss over jailbraking 1.1.3 I have a slightly different question I can't seem to search out an answer for...

I might have a v. 1.0.2 Iphone coming my way. I'm worried that I will ONLY be able to upgrade to 1.1.3 now that it's been released. Is there a simple way to upgrade an older version to 1.1.1 or 1.1.2 WITHOUT going all the way to 1.1.3?

Sorry, I'm fairly new to this

Thanks.

Earl
