I need to create a cellphone app that catches the phone-numbers of incoming calls. I don't need to actually do anything with the call itself. Just catch the phone-number. I looked briefly at PushRegistry first, and experimented with a tel:// protocol (since that's what's used to make a call using platformRequest). But it wouldn't install on my Sony Ericsson Aino, so I guess it can't be done that way.
I then learned that it seemingly can be done with JSR-253. But I'm having trouble finding any phones that supports JSR-253.
PhoneArena.com says Sony Ericsson Hazel supports JSR-253: http://www.phonearena.com/phones/Sony-Ericsson-Hazel_id4276/fullspecs
But Sony Ericsson's own white paper for Hazel doesn't mention JSR-253: http://developer.sonymobile.com/downloads/whitepapers/sony-ericsson-hazel-white-paper/
I'm thinking maybe there was a firmware update that included JSR-253? I don't have a Sony Ericsson Hazel to test on, and I don't feel like getting one if it won't work.
Anyway, the question is: How can I find a list of phones that supports JSR-253?
Thanks
