Hi! I have created a auction app. It works great in the simulator and is blistering fast. The app consumes Json-data from my web-page and uses no local data storage. However when testing the app on a Iphone 4 or Iphone 3g on then same WIFI as the computer, speed is not as impressive… (Budget: $30-$250 USD, Jobs: Appcelerator Titanium)
