Can't save any shsh!!!

[hb2010]

So my friend just got an Iphone 4 today with OS 4.2.1 and wants to jailbreak it, using tiny umbrella to save my shsh's it looks like I cant save any of them to cydia. Does this mean I can jailbreak the 4.2.1 OS that came on it but I just can't ever restore to 4.2.1 or downgrade? Or does this is can't jailbreak 4.2.1 at all and have to wait for 4.3? I'd appreciate any help I can get, thanks!
