With the launch of iPad and the jailbreak of it just around the corner, it is very important to have your SHSH files saved on Saurik’s servers to preserve the jailbreak capacity of this new device. This is very easy to do using a tool called Umbrella Firmware, available here.
It’s pretty much the same procedure as for the iPhone / iPod Touch, so you don’t have to type a lot. I remind you that you must have the ECID of your device at hand.
Basically you just have to run your version of Umbrella Firmware (Mac or Windows), type the ECID, and choose Saurik-Cydia from the drop-down menu, then click Submit. Done, you’re done.
Now, sit back, relax, and wait for the official jailbreak to be announced … we’ll keep you up to date.
