Hey folks moments ago @Pod2G Tweeted that:
Hey, @Lunch8ox tested RC5.4. Works well on Verizon. Thanks for the testing mate.
People were reporting that Greenpois0n was not working for them on iOS4.2.5 and iOS4.2.6 and some were reporting that it was wroking for them. So people who will be buying the new Verizon’s iPhone4 will be able to Jailbreak now Soon and enjoy the fun.
Till now it seems to be Untethered but we will confirm it and tell you.
