Restoring ziphone unlocked iphone

[crxd16si]

So my iPhone's battery wont last a whole day, and I unlocked it with ziphone. The question I have is, I want to return it to apple and is there a way they will be able to tell its been unlocked? I used the last button on the ziphone and put it into DFU and then I restored it back to 1.1.4 But I heard that doesnt put the bootloader back to 4.6? So is what I did good enough?

Thanks

if your original bootloader was 4.6bl and got downgraded with ZiPhone's unlock, then a restore wouldn't have changed that. you can use BootNeuter to upgrade it back up to 4.6bl. Do a search for BootNeuter. some people have put this on installer to download so you don't have to go through Pwnage if you don't want to
