I have a 1st Gen iPhone (yep, it's still going), and was wondering how info gets "pushed" to it through my MobilMe account, meaning when it syncs my email, iCal, and Contacts?

Not that it syncs correctly, in fact I've been loosing all sorts of info on my iPhone for sometime now.


Does the info get pushed via my cell carrier's data services?


Reason I ask is, my cell phone carrier recently started charging me for data services, claiming my phone is accessing the web. I NEVER access the web on my phone. I work from home so have no need to access the web via my iphone. Even when I go out, I don't do this either, since I can't afford a data plan. Still, they are claiming it's happening multiple times a day and it's because it's an iPhone. I think this is total BS, but need to proof before I call them on their bogus charges.

    Push goes over wifi or the cell data, with wifi having priority, assuming you have wifi on.

    Yes. If you're not connected to WiFi, data goes over the cellular connection. All supported carriers require a data plan with the iPhone. I'm pretty sure you can disable cellular data entirely, which is what you need to do if you don't have a data plan and don't want to be charged for using it, on iOS 3, but to tell the truth, it's been so long, I'm not sure any more. I've never had a reason to want to disable cellular data at all. When I travel overseas, I buy a cheap disposable phone and get a local SIM, so it's not an issue for me.

    Email, etc., will not go over regular cell service and visual voice mail does not work without data services either. What was probably happening was your phone would go into sleep mode, disconnecting WiFi, and then the phone handles data transfer through cell data.


    Do you have the original iPhone with the metal back that is not 3G? Is it on AT&T? Because if so you have also shut off your text plan.

    Why would you turn of WiFi? Your carrier doesn't charge you for that.

    That's how it works,  If you turn off wifi, if it needs access to the internet, it uses the carrier data network.  If they can't disable it, it's an app that's probably calling home or checking something.

    The reason they'll usually waive charges (to a point) is because they don't want to put up with the constant whining.


    If you turn off wifi and have MobileMe enabled and have push turned on, you will incur carrier data charges.  If you're not on wifi and they are enabled, you will incur data charges.

    I have a jailbroken, original iPhone, with the metal back, non 3G.

    I pretty much stopped reading after this. Scanned it to see if there was anything of any importance or not, but there isn't. You're using a jailbroken phone, which can't be discussed here per the terms of use for these forums. You're using an unsupported carrier. You obviously have no understanding of how smart phones and cellular data plans work. WiFi is NOT reliant on your cellular data plan. Turning off WiFi has absolutely no effect on whether the phone will attempt to use data services other than to make the one that would be free (WiFi) unavailable, thus, forcing it to use the cellular data service.


    Good luck.

    Oh Ho! Is that so? I turn off WiFi and that's when their data usage happens? So, I should leave WiFi on then. Hmmm, so even with WiFi turned ON there's no way to stop the phone from using data services?


    Yes, how the phone works, if you're on wifi, it will use that as your data connection.  when not on wifi, it will use your carrier data network.  WiFi has nothing to do with your carrier.


    So, any time you're on wifi, and you have push enabled or any service that is set to access the internet, it will  use your carrier's data network to do so.  If you've been turning wifi off, t-mobile is right, you were using their network.


    Since the iPhone is a smartphone (not a 'feature phone'), more than likely there is no way they can not have it on a data plan.  If you don't use it often, get their cheapest plan.  Otherwise, you're going to continue to incur data charges.  Most t-mobile data plans are only about $10 extra for a dataplan.

    Search the Internet for how to change the APN setting on an original iPhone to "Null", using the iPhone Configuration Profile(free download). This will completely disable ALL cellular data on your phone, regardless of what T-Mobile does on their end and what settings you have on our phone.
