Does Switzerland have a presence of shops or businesses offering phone repairs?

I have seen a few Iphone specific places, but nothing that caters for all, or, if not all, just other smart phones.

I was in the UK the other week and was reminded that all the mobile phone shops offer a repair service as well as their normal business of selling mobile phones, but the likes of mobilezone etc here do not seem to do this?

Is the only option to go through the service provider?
