hi there, i'm not very familiar with symbian, i just got some simple question

i recently came up with a J2ME SMS app for 3650, out of curiosity, if 7650 does not support WMA, can i come up with the same version (using C++) of SMS app and install in 7650? i mean if i send an SMS thru the MIDlet, will the SMS be recieved by the C++ app in 7650? and vice versa?
