ok ok standby for a newbie question.i just got me self this great phone just wondering can i use the p990i's wifi to access the internet using my streamyx account?

any of you know a device that lets you connect your phone to the car's speaker?so that you can play mp3s from phone. another thing you can also use it as a handsfree device so the caller can be heard through the car's speaker. my friend last time demo'ed to me once using his SE phone but i forgot what model.
