Is it possible to Upgrade an ipad 2 Version 5.1 to 5.1.1, or even downgrade to 5.0.1?

[J18Ways]

Hi, i'm a jailbroken user (have an iPad 3 Wifi only 5.1.1 jailbroken)

A few days ago, i bought a second iPad 2 wifi + 3g and it came with stock version 5.1 and i've read online that if you do not have the SHSH blobs it's impossible to upgrade/downgrade so i can jailbreak that ipad.

Anyone know of any ideas to do an upgrade/downgrade without SHSH blobs seeing as i can't get them?? Either version 5.0.1 or 5.1.1

Also on a side note, i saw this posted on youtube:

open up tinyumbrella and start tss server...
get sn0wbreeze and make a custom 5.1.1 ipsw...
Go into redsnow and do pwn dfu mode
Go into itunes...
Shift+restore and select the sn0wbreeze ipsw u made.
Done!

If i use that method will it work, i don't want to try doing it and end up having to mess up and restore to iOS 6...and wait an infinite amount of time until the iOS 6 jailbreak comes out.

Hope someone can help me with this problem Thanks!

Unfortunately, your second paragraph contains the truth; you cannot do anything to that iPad2 - other than upgrade to iOS 6.0.1 -without blobs. Never.

Sorry.
