We know the Dev Team is working hard on the iPhone 4 unlock. They have actually been pretty successful at it, as PlanetBeing was able to demonstrate last week. The problem the Dev Team is now facing is the number of fake iPhone hackers trying to impersonate them on Facebook or Twitter.
Those fakes often give misleading or wrong information. They clearly want to spread bad information, often with download links to malware.
MuscleNerd and the Dev Team made it clear today in a blog post that you should be very careful with what you see or read online. Basically, there are just a few people you can trust: @MuscleNerd, @PlanetBeing, @iPhone_Dev, and @Ultrasn0w.
To make things easier for you, you can simply follow me on Twitter, or just read this blog on a regular basis as I always share the latest news about jailbreaking and unlocking.
