Hi, with the imminent release of iOS4 I've sent to Apple a new app, ABContacts Lite, a reduced version of my other popular app ABContacts. The Lite version is free and uses the new iAd technology added to iOS4 to display some ads in a small part of the screen. With the app one can manage contacts and groups, send group text (this is also a feature of iOS4) and group email. The graphics look is very similar to the Apple Contacts app. Moreover the app supports multitasking and stays in the background; this means that even users with very big address book will not suffer for slow loading time with the exception of the first time. I've also sent to Apple a similar upgrade for my app [app]ABContacts[/app] that has many more features than this new Lite version.
