(adsbygoogle = window.adsbygoogle || []).push({}); Ok so I had to restore it but I had loads of apps on so once I went to the app store it said install on the apps I have previously bought but when I click it it then says buy and that's what makes me scared will it cost me again or not

You restored it

Yeah because it wasn't working properly

Yeah so the answer is no.

So it won't cost me m8

No if you have purchased a app from the app store and download it again you will not be charged again. The easiest way would be just to sync with iTunes again if you had your apps backed up.
