What sort of mobile phone runs AviatorCalc and Pilot Calculator software ?

You will need a mobile phone capable of running Java programs such as games. There are two specifications for such mobile phones. Nearly all new phones run the so called Java J2ME MIDP 2.0 CLDC 1.0  specification or better. Older or more limited mobile phones use the Java J2ME MIDP 1.0 CLDC 1.0 specification. You do not need to know what this means but you do need to know which type of mobile phone you have.

Which type of mobile phone do I have ?
