I have a Treo 600. Pretty old but it works. I was thinking of getting the iphone when it comes out but its not 3g. So I was thinking of upgraded to the Treo 750 which is 3g. I went into the Cingular / ATT store today and I wanted to know if they could give me some type of deal so the guy looks up my account. He noticed I had the media net unlimited which gives me unlimited internet for $20 month. He said they are starting to crack down on people who have smart phones and are using this plan for internet because for some reason it works when it shoulden't. I don't use internet excessively, but sometimes I do hook it up to my laptop and use it as a modem. I am just hoping he did not flag my account. Anyone have an issues with this or comments on the Treo 750?
