iOS 7 was launched a month and a half ago, but so far no solution has been launched tethered jailbreak for him, although redsn0w contains one bootrom exploit able to do this. Every time when Apple Lossless Audio CODEC (ALAC), released a beta version of iOS, the Dev Team updated their redsn0w program to allow a tethered jailbreak for terminals released up to iPhone 4. Although this year iPhone 4 remains the only terminal, from the old generation, capable of running iOS 7, for now redsn0w has not been updated and is not able to perform a tethered jailbreak for iOS 7.
We know that iOS 7 can be exploited through a jailbreak solution, we know that there are exploits that allow us to do this, but for now they are withheld for the release of the final version of the operating system. It is strange the hackers' strategy to leave the iPhone 4 without a tethered jailbreak, considering the huge popularity of the terminal, but probably everything is part of their plan to offer jailbreak solutions in the future as well.
