When i update my iphone to ios 7 it says unavailable?

I was trying to update my iphone 4 to ios 7 and it said "software update is not available at this time. Try again later." help? I don't know how to fix it

My ipad downloaded it but when i want to install it it says verifying update and then it says software update unavailable. Tried it like 20 times and getting the same message. It must be because alot of people are trying to download it.

Having the same problem. I'm trying it on my computer also, to see if it downloads it. Its seriously frusterating and apple knew this would happen but they didn't find a way for millions of people to download it. Honestly they're probably too busy focusing on iphone 6 instead of this.

What countries are you all from?

Mine says the same Entony. It's downloaded but won't verify. Just asked it to try again and looks to be going through. Fingers crossed!
