i'm not a programmer just a student but 2 days ago i made a java applet for a Roy-Warshall algorithm i learned at university and since my phone has java i was thinking to make a program for it? maybe a game? so this thing the windows phone sdk can help me? i only have a Nokia C1-01. and i don't use windows 7 or vista as it says in the system requirements. will there be a version for windows xp too? are there other tools which i could use to make something for my phone?
