iPod touch Update

[Mac7]

Just bought a iPod Touch 4G, it came with 4.2.1, is it impossible to update to 4.3.3 now?

Yeah, just plug it in to iTunes.

Yeah, just plug it in to iTunes.

Keeps giving me this. No error number either.

Oh, wait, I missed it. Yeah, if you want to upgrade to 4.3.3, you'll have to have the SHSH backed up from 4.3.3 ... Right now, you can only upgrade to the current version.
