Java on 7650 same as on 3650?

Hi experts,

I have written a small computer game in java. Now I finally had my hands on a new 7650 and willing to play the game on it. Can anyone give me some refs about writing programs for mobilephones?

Is the JVM on 7650 the same as other symbians? Do I need to rewrite a lot of code? (say, more than 20%?)

Cheers

BTW, where can I find a cracked miniGPS? :D
