Downgrade iOS 6 on pre-A5 devices.
Step 1: Download RedSn0w 0.9.15b1 or newer from here, Mac or PC.
Step 2: Connect your iOS device, and place it into DFU mode.
Step 3: Ensure that RedSn0w detects your device in DFU mode at the bottom of the main RedSn0w page. Click Extras > Even more > Restore > IPSW, and select the IPSW firmware file that you want to restore to. If you don’t have the right firmware file on your machine, you can download firmware files from our downloads page. RedSn0w should process the IPSW file.
Step 4: After the IPSW is processed and identified, you will be prompted to preserve your baseband. If you’re on an unlockable baseband, and you rely on UltraSn0w or a SIM interposer for an unlock, you may want to preserve your baseband.
Step 5: Next, it’s time to select the location of your SHSH blobs. If your SHSH blobs aren’t local, you haven’t fetched your blobs, or performed this restore before, you will most likely need to click the Remote option. This will fetch the necessary blobs from Cydia.
Step 6: Once your select your blobs, the restore process should begin, and you will be restored to the firmware you selected. If, however, you receive an error saying Couldn’t restore Mismatched APTicket, then your device will be kicked out of DFU mode, and the restore will halt. Don’t worry. Place your device back into DFU mode, and repeat step 3 again, and the restore should take off from there.

Pre-A5 means it doesn't have the A5 processor or higher, if you have an iPhone 4/iPod Touch 4th Gen or older you're fine.

I remember those days. The days before Apple only signed the newest firmwares.

No, the iPad 2 has the A5X processor. My mistake, didn't think about iPads.

This method won't work, but if you've jailbroken before on a previous firmware you can downgrade using iTunes and your SHSH blobs, google it.
But take that with a grain of salt, I don't have an iPad 2 and have never done any jailbreaking with one.
