While many will be happy to hear about the newly-released p0sixspwn iOS 6.1.3, iOS 6.1.4, and iOS 6.1.5 untethered jailbreak by iOS hackers iH8sn0w and Winocm, it would appear that the release is somewhat of a disappointment for pod2g, one of the well-known iOS hackers behind the evad3rs iOS hacker team that released the untethered iOS 7.0-iOS 7.0.4 jailbreak known as evasi0n7.
According to pod2g, p0sixspwn appears to use up a valuable root exploit that pod2g claims could have been used in future versions of iOS. It's also noted that it was an exploit found by comex.
iOS hacker pimskeks also notes that iH8sn0w and Winocm had at least two other exploits that could have been used instead of this one:

With less exploits available for future jailbreaks on future versions of iOS, this means that hackers will have to work harder to make up for lost exploits by finding more. This means that more time will be required, and this contributes to the long wait times for users in the jailbreak community.
There doesn't appear to be any official response from iH8sn0w or Winocm just yet.
