Iphone 4 Updatet baseband

[OkiiDokii]

Hey,
After a itunes update to ios5 my baseband it now on 04.11.08
I can't downgrade the baseband what can i do to work my sim?
Wait of a unlock from gevey or ultrasnow?


The tutorial of f4780y doesn't work any more :/

no, there is no way to downgrade the baseband that your device is now on... you would have to wait for one of them gevey or ultra to work,

What carrier is it locked to? and are you in the same country the iphone was bought from?
