iPhone 4 iso 4.3.3 to iso 5 preserve baseband question?

[Newbee123]

Hi, all.
I can use sn0wbreeze to create custom ios 5 (i.Annie showed me) but I don't have iso 5 SHSH saved . It means that I cann't request iso 5 SHSH from Cydia. So, how can I upgrade my i4 from iso 4.3.3 to 5.0 preserve baseband? I'm sorry if that is a stupid question.
Thank you.

You don't need SHSHs for iOS 5. Well you can't really get SHSHs for it anyhow.
