    As the title says I'm trying to downgrade my sister's iPhone 3GS. I was aware that a downgrade from the iPad baseband was made for the public. I downloaded it and followed all the steps. However my sister's iPhone is still on the iPad's baseband. She's currently on ios 4.33 and baseband 06.15.00. Is the problem that her iOS needs to be iOS 5?

    The version of iOS shouldn't really matter since everything is done inside of a "ramdisk."

    After a bit of investigating, it looks like you're not the only one with this problem, but there's no workaround or fix floating around. The only thing I can suggest is double-check and make sure that you selected "Downgrade from iPad baseband," and not "Install iPad baseband" (but that's probably not the problem).

    I guess I messed up then...
    I upgraded her phone to iOS 5. And I lost her pictures, texts, contacts, everything. And in the end the downgrade doesn't even work.
    :/

    That's not a problem; the iPhone 3GS and 1st generation iPad use the same exact baseband chip. In fact, baseband 06.15.00 was used for unlocking iPhones since around iOS 4.1 or 4.2.1.

    The OP's issue isn't getting 06.15.00 on his sister's iPhone though; it's downgrading from 06.15.00.
