iOS 7 is being beta tested by developers!

We all know about iOS 7. To be honest, I don't know it's consumer release date, but apparently, it's beta version is now available to developers. To be honest, I really don't know what to expect from it, but I have seen some screenshots.

Pros
1) I like the fact that it's gonna get better music controls. I like the idea of being able to scrub along the song even on lock screen. Probably my favorite announced improvement!
2) The better way to update sounds nice to me as well.
3)The new design certainly looks nice, at least to me. (You might have a different opinion here, though.)
4) iTunes Radio. Just... iTunes Radio. Wait, does it support net radio stations like Idobi Radio? Because if it doesn't support my favorite station, I won't use their "Radio."

Cons:
1)The new design may take a while to get used to.
2)Is iOS 7 Safari klutz proof? Because judging from it's description, I'd say it's not.
3)iTunes Radio is only available in US? (Apple's description has that below it.)I hope this gets fixed. Music should be available to everyone, 
regardless of their location and the place they live in.

I'm sorry this is short. But I wasn't able to find much reliable info online.
Sketchie out.
