Hello! My daughter has an 8GB iPhone 4 with firmware 5.1. She's been acting strange lately, and as a concerned parent, I'd like to jailbreak her phone in an attempt to keep an eye on her. Is there any way I can do an untethered jailbreak of 5.1 or at the very least downgrade the firmware? No, I do not have any of the SHSH files, as I was unaware she upgraded until it was too late. Please, I'll do anything to protect my daughter. She can't know that I'm doing this, so a tethered jailbreak won't work.
