    I basically upgraded my iPhone 4 to iOS5 when it came out, but now I am selling it because I have the 4S. Am I able to downgrade it if I download a 4.3 IPSW and restore to this version? Or am I hooped because the baseband would have been updated as well.

    Sorry I'm a little cloudy when it comes to this stuff, any help would be appreciated :)

    Yes, but only if you have your 4.3.X SHSH blobs.
