My iPod Touch 1st gen is not updating to any software. I am running on 1.1.5 which is super old but when I try to updat, it says "error 1604". I believe it was jail broken before but have since restored it. Does restoring clear everything because my screen is also dim and there are problems with jail broken iPod touches and screen brightness. I have tried 2.0 also 3.1.3 but have come up short. I need legit cites to download and install 2.0 at least to download apps. Can I also get some instruction plz as I am new to all of this.
