i bought me a new iPhone.
Now I am waiting for the parcel :)
I want to use this phone with my non-tmobile provider sim.
I dont know the baseband Version.
Are I am right?
Jailbreak = run unsignet software BUT still locked to t-mobile?
Yellowsn0w= Software unlock for all provider? But not with the new Baseband?
Is it possible to downgrade the Baseband?
Or is the only possibility a turbo sim card adapter?
