During the day yesterday p0sixspwn jailbreak for iOS 6.1.3, iOS 6.1.4 si iOS 6.1.5 has been released for all chip iDevices A5/A6, but as I told you, he has various problems. Some users who have performed jailbreak- using the program became unable to use a mobile data connection on their own terminals, or to access a 4G LTE network, and iH8sn0w conceived already a method to solve the problem, the procedure being explained below.
Basically an iOS file needs additional permissions to work properly, and this solution applies this, the easiest way to apply it is using MobileTerminal. Download the application from Cydia, log in as root using the command su and then the password Alpine, and then enter the command chmod 755 /var/mobile/ /var/mobile/Library/ /var/mobile/Library/Preferences/ and press the Return key. After performing the procedure, navigate to Settings>General>Reset and choose the option Reset Network Settings, after the reset things will return to normal.
An update for p0sixspwn will be released in the next few hours to solve the problem, but in the meantime you can use this method.
1) Install OpenSSH via Cydia (or optionally perform this as root in Mobile Terminal).
2) SSH in to your phone via Terminal (Mac/Linux) or PuTTY (Windows).
3) Type the following command:chmod 755 /var/mobile/ /var/mobile/Library/ /var/mobile/Library/Preferences/
4) Reset Network Settings (Go to Settings –> General –> Reset).
