I`m on 0.9.5. I can get the sim working only if I use airplane mode.
From what I understand airplane mode works in terms of switching off the voice network.
So basically, yellowsn0w is running, and once you turn on the voice network, it gets patched by yellowsn0w.
Is there any way to specify boot order ?

From what I can tell, if we can get yellowsn0w to boot before the voice network, airplane mode wouldn`t be needed.
