Well, here is something interesting. It seems that a Czech-based developer claims that Apple is preventing Push Notifications from working on unofficially (yellowsn0w or ultrasn0w unlocked iPhones).

Here is his quote:

“According to technical documentation, every Push application has to request the unique token from the Apple’s APNS servers to identify the device it’s running on. Thanks to that token, APNS servers always know which device is yours. The token can be understood as an IP address — the server has to know where to send the notification and for which application. APNS can also change your token regularly for higher reliability, so it’s critical that the application requests the token again on every start (or when enabling the Push feature) to replace the old one if new token is forced by APNS.

On any unlocked iPhone , the application requesting the token is stuck. APNS does not provide any response at all and the application can either cancel the request completely by automatic timeout or let user wait with the progress bar forever. Either way, the user will never receive any Push message, because APNS has not provided the token.”

Well, this may prove why the iPhone Dev Team can’t hacktivate Push Notifications. Well, us here at Limited Edition iPhone have Push Notifications working. [Read more →]
