My friend has a 16gb 2nd Generation iPod Touch thats still on OS 2.1. She wants me to jailbreak it for her so I'm wondering if its still possible to upgrade it to 3.1.2 instead of 3.1.3? I've read that Apple isn't signing for the 3.1.2 firmware anymore and they only let you upgrade to 3.1.3. Is there any way to get it to 3.1.2 instead? I've got the iPod2,1_3.1.2_7D11_Restore.ipsw file if it helps. Thanks!
