I just bought the Treo 300, and after looking at the plans for Sprint's network connectivity, they seem extremely steep. I noticed that in the preferences it appeared that I could set up my Treo to use a regular ISP to connect instead of using the more expensive Sprint service, but I've been having trouble with it. I keep getting a message saying that "The network is busy" with an error code of 0x1102.

It is strange that this worked the first night I tried it against Southwestern Bell's dialup number. Has anyone else gotten their Treo working without using Sprint's network?

Thanks!
