Open up cydia and look at the top of the screen it should list if u have shsh's saved and for what firmware.
Assuming u were jb before and clicked the "make my life easier" option on cydia.

If you are currently jailbroken and have old bootrom (yes to both I think), make or get a custom restore 3.1.2 IPSW, put your phone in recovery mode and use iTunes to select the custom restore 3.1.2 IPSW. Will bypass checks. You have to option+ (mac) or shift + (PC) the restore key to be able to browse to 3.1.2 custom restore IPSW.. It should start with 2,1......
Once you or even former owner if there was one, pushes Make my life Easier button, all SHSH for every new version of firmware is stored automatically. So yours was started when 3.1 firmware was signed and will keep collecting as new firmware is released (as long as you remain jailbroken)
