iPhone push notification
App developers are quickly integrating the push notification capabilities supported with the iPhone 3.0 firmware update. Pinger has released Textfree, an app that allows users to send and receive free text messages to or from any US cellphone. Push technology enables instant notification when the handset receives a message, while users can establish a permanent texting address. iPod touch owners can also receive messages from the US network via Wi-Fi, even without a phone number.
Tapulous has prepared an update to Tap Tap Revenge featuring improved two-player modes, online play and friend challenges. Ngmoco's Star Defense update also allows users to instantly challenge friends. Powerybase has developed NotifyMe, an app that uses push technology to send personal reminders for items such as to-dos, birthdays and shopping, among others.
Textfree is now now available from the App Store for $6, while a Lite version can be downloaded for free. Tap Tap Revenge 2.6 is available as a free download, while Star Defense can be purchased for $6. NotifyMe is still awaiting approval.
