[leer125]

hey i just flashed to no2chem 5067 rom and i love it except i wanna use opera 4.1 so i go to opera and download it and to make it work i had to go find some type of java emulator but the one iam using doesnt allow opera to be full screen. where can i find that java that comes with the stock from. or is there a way i can make it full screen i looked in the settings of opera but didnt find a full screen. also is there a way to make it my default internet browser? thanks
