Hey everyone, I was just wondering about the Gevey Ultra and will it work with an Iphone 4 on 5.1.1 with a baseband of 2.10.04. The Gevey website states: *If you are upgrading to iOS 5.0, 5.0.1, 5.1 or 5.1.1 you will need to preserve modem firmware version 4.10.01 when upgrading. Note that we don't offer phone support for preserving previous modem firmware versions on iOS upgrades. This is recommended for expert users only! Is this the only baseband that will work or are they just informing you need to preserve a baseband before this? If I need the 4.10.01 baseband can I upgrade to it. I can't find any real information on this so anything is much appreciated.
