I know the smartphone providers are now providing Push Notifications. I have searched and found Android, iPhone, Blackberry, WP7, Symbian are in the list.
But I want to know whether I can use Push Notification Technology on BREW handsets or not.
Any information regarding this question is welcomed.
No - BREW doesn't support anything like that, because BREW isn't designed for it (it's over 10 years old). You could use SMS messages instead.
