    You are SOL at this moment. Here is what you are facing;

    1. Gevey sim works with Iphone 4 with baseband up to 04.10. OS5 has baseband of 04.11.
    2. Unless you have SHSH blobs save, you can't downgrade firmware because Apple stops signing any firmware prior to os5 on Iphone 4.
    3. Even if you have blobs save, you can downgrade firmware, but baseband can't downgrade. Therefore, even you have an Iphone 4 with 4.x.x firmware, the baseband will remain at 04.11 and therefore, Gevey sim will not work on it.

    If you are talking about software unlock, there are none at the moment for Iphone 4 except those have baseband of 01.59.
