I just bought a HTC Fuze phone yesterday and I was checking out some of its features. I went over to the AT&T tab and tried the instant message feature and signed onto AIM but I forgot to log off. I don't have any internet plan or anything with AT&T so I was wondering if the AIM/MSN/Yahoo was part of any plans that requires me to pay extra or is it part of the wi-fi?
And the 3G network keeps staying connected, is that normal? It's connected to MEdia.net or something like that.
I forgot to sign off and left my phone on for a night so now I'm worried.

Please help, thanks.
