How long until apple releases ios 7

I want to update my iPhone 4S to ios 7 but apparently you can't get it yet I don't want to ruin my phone by doing it the complicated way. How long do I have to wait

It won't be out for like a month. Honestly, it's not that complicated to install it now. You just have to register your device's UDID with a developer account through a site like http://www.udid.in/.It's $5, and they even have a guide on their website to help you install it. Then you can try out the new OS before everyone else. That's how I got it on my 4S.

It's not hard at all, simply install the software. If it fails just restore the old one. Trust me it's worth it.
Really easy video will help you: short and sweet and it gives you the download link. No need for a developer's account:
