    just like the titles says, this is my last hope. i might have a preserved baseband where i could downgrade 04.11.08, but how do i check to see if i have on, thru cydia or so? thanks!

    preserved baseband usually refers to modifying a newer ios like ios 5.01 which normally comes with 4.11.08 baseband. this will only work if your iphone is currently at for example 1.59bb. so by installing an updated ios to a no_bb 5.0.1 firmware, the current baseband is preserved.

    once you already have 4.11.08 bb on your iphone, there is no downgrading back to 1.59 bb.
