Hi,
I did a very small app which downloads files from a server. iPhone 4 supports background processing of the app that is the app goes in background when user switches it.
Here is my question, if my small app developed on iPhone 3.1 based stuff (build to phone by changing to iOS 4) is allowed to run in background, will my app still continue download procedure ? or I should write specially for iPhone 4 for using the background processing capability
