hi, i bought a used first gen iphone that was already unlocked and jailbrokened. I'm planning to install cydia 3.0 but i would like to know what kind of unlock i have on my device. Bootneuter does'nt seem to be installed on my iphone. Yellowsnow is installed but it is only for 3G. Right?
Can the iphone be unlocked by another mean than software?
Will it still be unlocked if i upgrade to cydia 3.0?

thanx a lot
