Preserving the baseband allows you to continue using IOS Sim Gevey 5b2

As we have told Gevey SIM cards have stopped working on the second beta of IOS 5, but s and found that if you update a custom firmware created with the latest version of Sn0wbreeze you can still use your card and thus liberating iPhone with any carrier.

Sn0wbreeze keeps your baseband before updating, so the card still works, so if you have a card 5b1 IOS Gevey you know you have to update Sn0wbreeze.
