The developers at Chronic Dev Team have issued yet another jailbreak tool, the Greenpois0n RC5.4 aimed at allowing Verizon iPhone 4 customers to set their smartphone free.
The Verizon iPhone 4 runs on iOS 4.2.6 and the new firmware adds the new personal hotspot feature; it should be available both for Mac and PC users - still no Linux version.
Users who have tried it say that it shouldn't take more than one minute to do the jailbreak but warn against the ever-present possibility of bricking the phone. The firmware can be downloaded here for Mac and here for PC.
The Verizon iPhone 4 is set to be shipped on the 10th of February with thousands of customers having purchased the entire initial stock in less than two hours.
