  1. Re: How to find current Location using LBS library in java me?

    All locations have a latitude and longitude. Not all locations have a good GPS signal... e.g. in streets with tall buildings, under trees, indoors. This is why we ask if you can get a signal using...

    Re: Java ME and Network Based Positioning

    Choosing "Network Positioning" in the positioning system triangulates from multiple cell ids (assuming that the network operator supports it, which in the US is pretty much all of them). There is no...

    Re: GPS vs A-GPS

    Definitely correct.

    Again, the marketing material is not actually "wrong"... A-GPS *IS* GPS, with added functionality. The marketing material is right in both cases, it's just stated differently...

    Re: Java ME and Network Based Positioning

    It can't, you misunderstand me.

    The documentation for com.nokia.mid.countrycode says that it returns an ISO3166 code (e.g. "GB", or "US", or "CN"). In other words, as far as the documentation is...

    Re: Java ME and Network Based Positioning

    Just to make sure that I understand. You're saying that when you use com.nokia.mid.countrycode you get a numeric value back (e.g. "234" and not "GB")?



    There are a couple of examples where...

    Re: Java ME and Network Based Positioning

    Unfortunately, the cell id is only half of the problem. It's pretty useless unless you also know which country you are in and which network operator you are connected to.

    I'm not sure this is the right way to look at it. A-GPS is GPS with some additional features that Assist in obtaining a location fix more quickly.

    A-GPS is GPS plus extra functionality. The fact...

  20. Re: what kind of technology mobile mail clients using

    I suspect that your network operator is blocking any packets sent to external servers on port 25. You should not be using SMTP, try using SMTP-AUTH instead (port 587).
