Do advice me to install iOS 7 on my iPhone 4s?

I have a jailbroken iPhone 4s running 6.1.2… And i really like the new iOS… I can install the beta version… What's your advices?

If it was me I would do it

You can't install iOS 7 unless you are a registered developer with Apple which is $99 a year. Without that there's no legal way to use the new iOS, you will just be stuck in activation mode, making your phone unusable.So, wait the few months for the official release to come out or pay up.

Well, if you do upgrade, your iPhone will no longer be jailbroken.
