Redsn0w has just been updated to beta 4 to support the latest iPhone OS 4 Beta 4 firmware. iPhone OS 4 Beta 4 was released by Apple last week, which since Beta 2 has closed the jailbreak loophole used by Redsn0w 0.9.5b1 and b2 to jailbreak OS 4. But with this latest version of redsn0w, you should be able to jailbreak iPhone OS 4 again on iPhone 3G.

Most of you must have heard about the thunderst0rm team who claims to have got an exploit+solution to jailbreak and unlock all device (iPhone, iPod and iPad) on iPhone 3.1.3 with 05.12.01 baseband. Today, they have posted a new video which shows the final test build in action. According to them, if everything goes fine, they will release the program Tomorrow.

The next-generation iPhone is expected to be unveiled in June at WWDC 2010 which will be held at Mascone Center in San Francisco. The real deal as we informed you earlier, has already been leaked in the wild.
