Devteam’s MuscleNerd today said that iPhone 4 can be unlocked, which is a very good sign for users like me who doesn’t want to stick to one carrrier :P. MuscleNerd also said that they are coming with unlock tool for iOS4.0 by next week. Apple is releasing iOS 4.0 on 21st of June. Today they’ve also released the new beta version of redsn0w 0.9.5 which jailbreaks iOS4.0GM. It also lets you to individually select whether multitasking and homescreen wallpaper are enabled. It also adds battery percentage and verbose boot mode options( Enabling this option will show you the messages that takes places while booting iDevices, just like what we see when we boot Android on iPhone).
