I have a localstorage which holds data as a cache. Everytime I start my webapp, i ask the server if new data is available. if so, I set up a store with jsonProxy, collect the data and copy it from this store to the localstorage.
Is there any better method then iterating over the jsonstore data and copy it record by record into the localstorage? This is not the fastest operation on the iphone and I currently try to find a way which performs faster than this..
