This was Thomson Reuters first iPhone application that we built and was built on top of the Spotlight APIs. This project resulted in a lot of interesting discovery about cellular network latency and delivery content over the limited bandwidth. The characteristics of the NewsPro application, which allows offline reading, meant that there were potentially a huge number of requests being made for all the articles and their subsequent images to download all the content onto the phone. Given the network latency between requests on the cellular network this was not acceptable, so to improve the performance the Spotlight APIs were updated to enable batching of content so once you got a connection as much content as possible could be downloaded to the phone in one go.
