How to get ios7 without a phone number on my iPhone?

So i have and iphone that doesn't have a number connected to it but i still use it like an ipod. Will the update for ios7 come later or not at all? My dad got his and we have the same phone. Can i not download it because it doesn't have a phone number connected to it?

Maybe plug it into a computer that has iTunes. You might be able to get it through there.

It depends on the type of iphone you have (4g, 5g, etc.) On the ios 7 website it shows what is supported. For example: ipod touch 4g can't get ios 7 (really stupid) but the ipod touch 5g can.

You can download iOS on the computer from
