Apple begins testing high density push notifications

Push technology will allow iPhone applications to receive messages, updates and other data while not actually active

Apple has begun testing its servers to see if they can withstand high demand for the iPhones next OS 3.0 push capabilities.

In an email sent out to developers of 3.0 beta apps, Apple asked them to download a pre-release version of the Associated Press' iPhone App. The test, which should run for a week will put Apple's servers through their paces to ensure the smooth service that is vital for the push notification system that many future Apps will rely on.

Push technology will allow iPhone applications to receive messages, updates and other data while not actually active, essentially allowing them to run in the background. This is seen as important technology for future iPhones running the 3.0 operating system as it should provide the user with both a smoother experience as well as possibly helping the phones battery life. 3.0 is thought to be the operating system of the much rumoured next generation iPhone, which is widely expected to be launched at Apples developer conference next month.
