Was it ever alive? I remember it being Wait and Pap, and nowadays the mobile phones usually have a "real" browser like Opera Mini or Safari.
I just wonder: Since WAP was for web pages, what Apps did you develop? It is a Web Server technology, not a client side one?
The alternatives are the SDK of the phone in question (iPhone, Symbian, Windows Mobile) or Java (J2ME) which is theoretically compatible with more phones, but still requires a lot of testing due to different screen resolutions, the existance of a keyboard or not etc.
