Question about 3G connection behavior

[Nessus]

Hello I'm new to the Treo and Windows Mobile as a pocket phone. I notice that the first time I browse the web, or send/receive mail, the Treo 750 shows a little bubble that it's connecting to AT&T's 3G network.

However, after I'm done (say by closing the browser program), it still shows it as connected (with the little double arrow thing up on the top task bar). I can click the icon and select disconnect manually, but it wants to stay connected.

Is this normal behavior? Is it ok to leave it "connected"?

Thanks,
Sorry if this is a dumb question.

If you leave it on and have an unlimited data plan its okay other than it will drain the life out of your battery quickly. Make sure you disconnect and close not minimize the program. tap and hold the ok button and a list of open p-rograms is listed close yopu web browser.
