A common trick in this kind of situations is to pass a random string in the querystring, This tricks the browser to think that the request is different and therefore you bypass the cache.

I came across this very same issue when a .NET site I worked on was caching web service requests to such an extent that it was affecting my site functionality. This seems to be a common trait in iOS6.

This StackOverflow post should help you: Is Safari on iOS 6 caching $.ajax results?

I have written some blurb on my experiences on this issue: http://www.isurinder.com/blog/post/2012/09/24/iOS-Safari-Browser-Has-A-Massive-Caching-Issue!.aspx

By passing a full time-stamp to your service should solve your problems.
