OK, I am running the GM version of 3.0 and overall it is working well, and is as stable as the last couple of Betas. My question for you today is a simple one, and a point which I feel is integral to the future success and development of the iPhone. After watching the WWDC Keynote in full, I can see that the Application Developers all have plans to include the push notification service into their apps. When will the push notification services commence? Everyone says that the applications that are out there now are fully compatible for 3.0. Does this mean that they already have the settings included for the push notifications? I have checked all the apps that I have, and in their settings there are no new features to chose your push notification services. The most important app that I think would be the 'big attraction' for apple is to get Skype working in this way. Will we be able to have Skype running constantly in the background to receive VOIP calls (when within WIFI), or will this service never be available? Also realistically what would the implications be on the battery usage running such a demanding app constantly in the background? So the main question is, when will we be seeing these things starting to work? For IM apps, the iPhone is lagging behind the other manufacturers like BB. With BBM they have that market secured, and Apple have to use one of their innovative new advertising schemes to sell their new IM capabilities with an App like Skype, which has the potential of being much more powerful than BBM.
