So I just got my first iPhone, an 8 gig that the previous owner had already upgraded to 2.0. PwnageTool had just come out, so I couldn't wait to apply it to my phone. And I did it - successfully! It's working with T-mobile without a hitch.
Except — it's kind of crashy. And I didn't realize that all those wonderful jailbroken apps had to be ported. So now I'm thinking I'd rather downgrade to the 1.1.4 jailbroken/unlocked firmware.
The question: can I basically apply the same procedure as outlined here
Hack that Phone - Downgrading 2.0 firmware to 1.1.4 firmware, even though that's for downgrading an *un*pwned 2.0?
Thanks!
