My ipad 2 (wiFi/GSM) is now in iOS 5.01 is there a way for me to upgrade to 6.1.2 now and then jailbreak it. I understand that the only one being signed by apple is 6.1.3
Nope. Even if you have 6.1.2 blobs, unfortunately the iPad 2 is not susceptible to any on-board exploits that would allow you to install a custom firmware like you can on the older devices. However, if you do have iOS 5.1.1 blobs, you can use the iOS 5.X re-restore feature from RedSn0w to upgrade from 5.0.1 to 5.1.1 if that makes a difference for you.
