    How can I upgrade my iOS to 4.3.3 when I'm on the new broadband 06.15.00 and also have the iPad baseband? As I understand I can only install custom ipsw's, is that correct?

    Best I understand, you won't be able to do it. Apple is no longer signing 4.3.3

    I do have shsh blobs and I tried to upgrade to 4.3.3, but that was where I had many problems. It was tethered version, I couldn't boot the phone without redsnow and after a while a phone just turned off and went into DFU loop which I couldn't get it out of it. I got errors 28 all the time. Drained the battery and solved the problem.
    Now I'm on 4.1 which seems to be the only firmware that my phone will accept and I don't even know how to come back to 4.2.1 now! :/
