iPhone-Dev team have released Redsn0w 0.9.10b8 to save and backup BB unlock tickets which are generated by SAM unlock.
With this latest version of Redsn0w you are not required to manually backup activation tickets but in just few clicks.
As per iPhone- Dev Team-
Redsn0w 0.9.10b8 adds the ability to backup arbitrary directories or files from your device into a zip file on your Mac or PC. The new button is Extras->Even More->Backup and it requires your device to be jailbroken with the afc2 service enabled (most jailbreaks include that). By default it will backup your activation records from /var/root/Library/Lockdown, which is useful for everyone taking advantage of today’s SAM unlock using Loktar_Sun’s trick.
