Can I save SHSH blobs off another jailbroken phone?

[braminc]

My girlfriend has a jailbroken Iphone 4 same as me running 4.3.3 AND has 4.3.3 SHSH marked as saved in Cydia (mine does not). Can I save her Cydia SHSHs to tinyumbrella on my mac and then restore to that? I really want to restore due to these problems I'm having Springboard repeatedly crashing, and reboots acting CRAZY and 5.0.1 just doesn't sound like a stable enough solution. Wondering if SHSHs are specific to the hardware of each device in some weird way?

Also, I noticed Cydia has only saved for her 4.3.3 and 4.3.5 while mine has already saved blobs for 5.0.1. I understand hers having older ones saved (as its been jailbroken longer) but I don't understand hers not saving the newer blobs. Does this make sense? What am i missing?

Nope. Shsh are device specific.

Thanks Simon. I guess I should've known that otherwise everyone would just be sharing their blobs online...?

Is it possible for you to comment on the other thread i linked in here? I have no replies and am totally stumped...
