IPod Touch 4G 32gB

[coldfront]

I just purchased a Ipod Touch 4G 32gB, right now it has 4.1 Firmware on the Ipod. I've been searching for jailbreaking my Ipod to 4.2.1. But whenever I tried to restore it with the 4.2.1 firmware I get an error that says This device build can not be upgraded. I went into /private/etc/hosts on my mac and pointed the gs.apple.com to cydia servers. I read somewhere that apple isnt signing 4.2.1 anymore. Restart Itunes and i still get that same message. Any help would be nice thanks.

Download tiny umbrella. Connect your device and press save SHSH. The SHSH that are saved are the firmwares that you can restore to.
