The iPhone Dev Team member, MuscleNerd, has warned iPhone unlockers to avoid the latest iOS 4.3 firmware update from Apple. The hacker has confirmed on Twitter that iPhone unlock will take much time than expected and those who have updated their iPhones to 01.59.xx baseband will have to wait for longer duration.

MuscleNerd: Ultrasn0w unlockers should know the drill! Don’t let iTunes trick you into installing today’s 4.3 iOS. Just say no!
MuscleNerd: Sorry, there’s no news on the i4 unlock for those who lost 01.59 (or never had it). It’s taking longer than we wanted
Just to be on the safer side, developers and hackers have not developed any jailbreak or unlock tool for iOS 4.3 firmware, so please stay away from harmful guides and methods published on the internet. These untested guides can potentially brick your valuable devices.
In case you don’t care about the jailbreak and unlock, you can download and install iOS 4.3 update on your iDevices. The direct download links are available here.
