    So my iPhone 4s is jailbroken and I want to update to 5.1. I dont care if it removes my jailbreak. I've been trying to update but every time I get, "This device isn't eligible for requested build." I've tried putting my iPhone into DFU mode and restoring but it still doesn't work.
    Oh and I've also tried update straight from my phone but I receive the following message:" An error occurred downloading iOS 5.1."
    Anybody know what to do?

    I used to be on 5.0.1 but decided to upgrade to 5.1, so I installed iTunes 10.6 plugged my phone in and did a restore, then updated to the new software. No problems here.

    Check your hosts file for any references to gs.apple.com and remove them (Google how), then restart your computer and restore via DFU mode. If this doesn't work, try another computer.

    Host file?

    Sorry guys, I was always an android person.

    What's the host file and where do I find it.

    Basically I have an IPhone 3GS jailbroken. My girlfriend updated it and now it wont sync or recognise Itunes to activate it once again.

    Anyone got any ideas?? Need some help and would really appreciate it.

    Thanks,

    Paul.
