For future (tomorrow or today) White iPhone 4 users, limera1n is NOT patched and has no difficulty with current jailbreaks.Chronic:
to those asking, white iPhone 4 IS vulnerable to limera1n still. thanks @dpdesilva!But must remember that new baseband of iPhone 4 is not unlockable yet with software based ultrasn0w, but you can unlock your iPhone with hardware based unlock solution like GEVEY, REBEL and TurboSIM interposer.
