How do i save them off the device.Then once the newest Redsn0w is released, you should be able to restore to 5.1.1 firmware
I know upgrading won't repair it but it will need the jailbreak removed to take it to a Apple store to the genius bar and i take it my only option is ios 6 now no way to restore to 5.1.1 without the jailbreakTry cleaning out the 30 pin port on bottom - very carefully and gently.
Upgrading the firmware will likely not fix the charging issue (either debris or hardware - bad or bent pin)
As long as the hash is shown in Cydia, it is saved.
No need to worry about it, however, if you want it on your computer, download TinyUmbrella, Advanced Tab, check request SHSH from Cydia, will dl it to your hard drive
