You should read that! All explained by f4780y.
We cannot use SHSH Blobs to up/downgrade on 5.0 or higher, but maybe we can in the future so it's a good idea to safe them!
Search for TinyUmbrella, download the program, connect your iPad2 to your PC and safe the blobs.

downgrading is possible with blobs(wifi only)....even with 3G iPads....

I can see it in your sig and that's what pushed me over tbhf4780y said:For info, both my iPad2 and iPhone4S are currently running 5.0.1
Todd M said:Too bad they don't have an update for the 5-row keyboard. Tried to load it on my wife's iPad1, and it doesn't work, since it's designed for 4.x :-( It worked fine on hers before, and is on mine now, but no dice on 5.0.x. That's a BIG loss for me. I can wait for SB settings, but 5-row and ScrollingBoard are big losses for me until pod2g makes us happy...

Everyone should upgrade their devices to 5.0.1 (except unlockers) now while they still have a chance!!!
What do you guys think?

We can't upgrade with blobs even if we have downloaded the firmware version straight from apple and we have the blobs 'saved' by tiny umbrella, can we?
