ITunes Radio temporarily unavailable for more than 24 hours, help!

Question

So, since yesterday afternoon iTunes Radio just turned off all of a sudden.
I updated next day the ios7 was released officially so I think Ive used iTunes Radio great for almost two days or so.
Then, the radio just suddenly went off saying
"iTunes Radio temporarily unavailable. Try again later."
Ive googled everywhere including every question here.
1) I use U.S. account so the location doesnt matter
2) Ive done several hard resets, including network reset once
3) Ive signed in and out repeatedly for several times like over 10 times, it doesnt work at all
4) I also waited for a day thinking that this problem is just because of some sort of jam, like many people crowded for this service
It works really well on my Windows PC, actually Im turning on the radio on my computer right now. Its such a great service for me.
But it just doesnt work on my device! I use iPhone 5, my iTunes is, as you'd already know, 11.1. Updated iOS 7.0. Never used a Beta.
Somebody solution please?
Should I just wait more or please tell me how youve solved if you had this problem too and have already solved!
iOS 7 rocks

Answer 1

I had the same issues with iPad itunes radio. I called and was transfered to a senior advisor at Apple who has cheerful and knowledgable but couldn't fix it.  I searched around my devices and came across something that happened to work. Without explaining too much of my situation, here is what worked for me.
Attach iPad to computer with caple, open itunes.
In the Summary tab, under Options, check the box "Sync with this iPad over Wi-Fi"
Voila.
I've read many forums with users who offered a fix, but it didn't work for me.  If this doesn't work for you, I apologize. This is my first post in Apple forums. Perhaps there's another setting I already have configured that needs to work in conjunction with this.
