Don't know much about PDA's, so can't help direct with your question. Although AOL do not offer tech. support for several things, "Networking being just one", it doesn't mean they won't work with AOL. I think that they are more likely than not getting round to offer their own method of connecting.
Meanwhile if one of the forum members has not got the answer to your question, then go into AOL's own help forum and message boards, if the answer is not already there, then it won't be long before one of them will come back to you with the answer, they do with networking questions, and it works just as well as with any other ISP. j.
