iPad Help and questions about upgrading

I have 5.0.1 and 6.0.1 shsh blobs listed on my cydia . and I'm currently on jailbreaked ipad 2 ios 4.3.3 . I want to upgrade to 5.0.1 because there's games that I wanna play that are only compatible with ios 5 and up . is there really no way to upgrade to 5.0.1 ? :/

 

Thanks ! by the way , why can't I fetch my shsh ? I want to fetch my current ios shsh (4.3.3) just in case something goes wrong .. but I just can't choose the option on redsnow .

EDIT: Here's the thing . I decided to just update to 5.0.1 anyway . but it asked me for any 4.x.x shsh that I do not have . but I AM on a 4.x.x device so .. is there a way to do this or there's really no way to upgrade ? :/
