Does a push notification use wifi if my iPhone was asleep?

When my phone is awake all Internet access is via wifi. The wifi turns off when the phone sleeps and then starts again when it wakes up; BUT there is a slight pause. So if my phone is asleep does the push notification wake the phone up then wait briefly for the wifi to connect before accessing the Internet? Or does the push notification "see" that the wifi isn't immediately available and start a 3G session?

If all you did was remove it from the device list (by clicking the "x" next to the device name), it should reappear on the device list automatically if it ever goes back online. Read point number 3 under "Remove an iOS device...on which you can't turn off Find My iPhone" here: http://help.apple.com/icloud/#/mmfc0eeddd.

Email push notification takes longer than on iPhone

Hi,
On my iPad 3 with iOS 5.1.1 the push notifications for gmail (exchange) take several minutes to arrive whereas on my iPhone 4S with iOS 5.1.1 the
Push notifications are instantly. I have already tried deactivating my iCloud account and retting my network settings but it doesn't make any difference.
Anybody experiencing the same issue?

Today the push notification for gmail on my iPhone was slow too. Took about 2 minutes after I've sent it. The official gmail app got it instantly.

Why can't i use wifi on my iphone 4s after i downloaded IOS7

why can't i use wifi on my iphone 4s after i downloaded IOS7?
thankful for answer!

Well, there are probably dozens of possible answers based on the nature of the problem, so a little more information would be useful.
Is the WiFi switch greyed out? If so, see: http://support.apple.com/kb/TS1559
Is the problem with only one network? If so, reboot the router by removing all power from it for about 30 seconds. Even if other devices still work on that router (the router and iPhone may have gotten out of sync on the time remaining on the iPhone's IP address lease).
If the WiFi switch is not greyed out, but the phone doesn't find any networks, go to Settings/General/Reset - Reset network settings.
If that fails, go to Settings/General/Reset - Reset All settings.
And if the problem is not described in this message please provide more information.

Hi, anyone knows how to using airdrop between mac and iPhone 5? My mac was using mavericks and my iPhone was using OS 7. There is airdrop icon in my mac. And already on. But it is searching constantly. Even my airdrop in iPhone already on for everyone.

Yes, you can use it for Mac computer > Mac computer or iDevice > iDevice. It's because they have different operating systems.

My wife's new iPhone was automatically backing up to iCloud. Now my 5mb limit is not allowing me to get my email. I turned off the automatic backup, but I do I get the storage capacity back?

Turning off automatic backup doesn't delete anything from your account, it only stops it from continuing to back up to iCloud. If you want to reduce your iCloud storage, this article provides some suggestions: http://support.apple.com/kb/ht4847.

Use of Push Notifications between Wifi and Cell Data

Is there a way to set the phone to automatically have push notifications turn ON when you're on WiFi and OFF when you're on cell data? I dont mind recieving them, but it would be nice if there was a preference to recieve them only when on WiFi. Anyone know how to do that?

The iPhone priority for a data connection is: WIfI>3G>Edge>GPRS. Note: While in sleep mode, unless connected to a power source, iPhone will disconnect from available WiFi & use cellular data for all data needs.
But my iPhone 4 definitely is using 3G when wifi is available, even switching to it when having been on wifi. For me this has only been happening since we started receiving 3G and 4G in our area. Used my full 200 meg data plan in one day when I normally hadn't come close to that all month. My settings were definitely set for using wifi and wifi was definitely available (was using it with my laptop). My internet is only 1 mb so I wonder if it chooses 3G or 4G because of speed. If so, this is a problem for me. If not, there is another problem.

Problem sending Apple Push Notification using Java and REST.

Hello there,
Am using the javapns library to send an Apple Push Notification through a REST based web service...
Here are the steps that I have completed:
iPhone Developer Program Portal (IDPP):
(1) Created the App ID and APNS based SSL Certificate and Keys.
(2) Created and installed the provisioning profile.
(3) Installed the SSL Certificate and Key on the server.
(4) Set up my iPhone app to register for remote notifications.
XCode:
Was able to obtain my device token when I built and deployed my app onto my device.
As soon as my iPhone app deployed, the dialog came up on my iPhone indicating that my app would like to send push notifications and also asked for permission to allow them.
When I invoked my web service, through my Log4J statements, I was able to see that my REST based web service was indeed invoked but I never received a push notification on my iPhone app!
ApnsManager class:
public class ApnsManager {
    /** APNs Server Host **/
    private static final String HOST = "gateway.sandbox.push.apple.com";
    /** APNs Port */
    private static final int PORT = 2195;
    public void sendNotification(String deviceToken)
    throws Exception {
       try {
           PayLoad payLoad = new PayLoad();
           payLoad.addAlert("My alert message");
           payLoad.addBadge(45);
           payLoad.addSound("default");
           PushNotificationManager pushManager =
              PushNotificationManager.getInstance();
           pushManager.addDevice("iPhone", deviceToken);
           log.warn("Initializing connectiong with APNS...");
           // Connect to APNs
           pushManager.initializeConnection(HOST, PORT,
           "/etc/Certificates.p12", "password",
           SSLConnectionHelper.KEYSTORE_TYPE_PKCS12);
           Device client = pushManager.getDevice("iPhone");
           // Send Push
           log.warn("Sending push notification...");
           pushManager.sendNotification(client, payLoad);
           pushManager.stopConnection();
       catch (Exception e) {
           e.printStackTrace("Unable to send push ");
RESTful Web Service:
@Path(ApnService.URL)
@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
public class ApnService {
    public static final String URL = "/apns";
    @GET
    @Path("send")
    @Consumes({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
    public String send() throws JSONException, IOException {
        String msg = "";
        try {
            log.debug("Inside ApnService.send() method.");
            log.debug("Sending notification to device");
            ApnManager.sendNotification("32b3bf28520b977ab8eec50b482
            25e14d07cd78 adb69949379609e40401d2d1de00000000738518e5c
            000000003850978c38509778000000000000000000398fe12800398f
            e2e0398fe1040000");
         } catch(Exception e ) {
               e.printStackTrace();
               msg = "fail";
         msg = "success";
         StringWriter sw = new StringWriter();
         JsonFactory f = new JsonFactory();
         JsonGenerator g = f.createJsonGenerator(sw);
         g.writeStartObject();
         g.writeStringField("status", msg);
         g.writeEndObject();
         g.close();
         return sw.toString();
}Now, when I deploy my app to my app server and open up a rest client and type in:
http: // localhost:8080/myapp/apns/send
The rest client returns this:
HTTP/1.1 200 OK
The following log messages are outputted to my console:
01:47:51,985 WARN [ApnsManager] Initializing connectiong with APNS...
01:47:52,318 WARN [ApnsManager] Sending push notification... However, I don't receive the push notification on my app (residing on my iPhone)!
Am really stumped at this point...
What could I possibly be doing wrong? :(
Is it a problem with the way I set up my RESTful web service (sorry I am a newbie to REST)?
Would really appreciate it if someone could assist me with this...
Thank you for taking the time to read this...

Please show me where is answer for this..

Does my push notification work properly?

When I firstly install and open a new App, some App which supports for the push notification will ask me to allow the push notification. Then If I choose don't allow, all notification fuunctions should be turned off, or not?
What I found is when I choose do not allow notifcation, for some App (it is likely to be a new release App) it was turned off only Alert style. The rest notification functions were still turned on, such as notification center, badge and sound.
However, for some App, such as facebook, when I choose don't allow notification, all notification functions were turned off.
So I don't understand why I got the different setting when I select "don't allow notification" after first install and use. I know that we can go to setting and set it manually, but I am not sure whether my iphone work properly, or not?

Not sure what 'goes crazy' means but it most likely should not do that. Try a reset... press the home and sleep/lock buttons until you see the Apple logo, ignoring the slider. Takes about 5-15 secs of button holding and you won't lose any data or settings.
Also try it plugged into another outlet (on another circuit) and/or try another charger.

Push notification over WIFI networks

I have some how a weired problem with push notification, it works fine on some wifi networks but not on my home wifi, for example, when I enter my sisters apartment the Push notifications starts flying in from all application (local apps and internet push like emails ..etc), whereby in my home network I don't receive any notifications, I checked the setup of both networks and didn't notice any substantial difference in the two setups.
Appreciate all your support

I have the same issue, can someone assist ?

WP8 SL and WP8.1 SL app push notification using wns

Hi,
I am new to windows phone push notification. I am aware that there are two service which can be used for push notification WNS and MPNS(Server). I have a silverlight app for both windows phone 8 and windows phone 8.1. Doubt I have, Will WNS work for this
app? If yes any client side changes are required to receive the notification or it will work with the old MPN client implementation used for WP8?

MPN Notification works on Windows Phone 8.0 and Windows Phone 8.1 Silverlight apps. WNS Notification Service works on both Windows Phone 8.1 Silverlight and Windows Phone 8.1 Runtime apps. So you can choose either of them.

Thanks for reply,
So you mean to say if I have single app for WP8 SL and WP8.1 SL I can not go with server implementation using WNS.
According to slides at link http://channel9.msdn.com/Events/Build/2014/2-521(Silde no- 11), it says existing MPN code needs not to be changed. So I suppose existing MPN code(Client) should work with WNS server side, Please correct me if am wrong.

In the Apple Push Notification Service,How long does a push notification sit in queue before being removed?

Official developer documentation isn't clear about this.
Apple Push Notification Service includes a default Quality of Service (QoS) component that performs a store-and-forward function. If APNs attempts to deliver a notification but the device is offline, the QoS stores the notification. It retains only one notification per application on a device: the last notification received from a provider for that application. When the offline device later reconnects, the QoS forwards the stored notification to the device. The QoS retains a notification for a limited period before deleting it.

This is an iPad user to user forum, so you are not addressing Apple. We have no way to know what and when Apple will do something.

App does not send push notification when app gone live but was working fine when tested locally?

Please help us to get this solved. We tested the webserice URL which works okay. Port 2195 is also open. APN certificate is also not expired. What could be the problem that app when tested before live was sending push notification and when it is live, it has stopped!?

This would seem to be a question better posted in the App Developers forum.

IMessages, Facetime, push notifications not working on new iPhone 5!

Hello Community,
I just upgraded this afternoon from my iPhone 4 to a new iPhone 5. I am currently connected to my wifi network and just noticed iMessages and facetime wont work! I tried signing in using my apple id and it says check your connection and try again or waiting for activation. I know there isn't an issue with my apple ID as i used it on my old iphone 4 and just purchased some apps in the store and it worked great! wnl
Also, the apps I downloaded are telling me to connect to iTunes to recieve push notifications, but push notifications are on for the apps! I also connected and synced my iPhone with my computer to try to solve all issues stated above, no dice. I realize these questions have been asked several times, so sorry to repeat a thread! Any help appreciated.

Hello there M.air.21,
I think I have the perfect article for you. It's named iOS: Troubleshooting FaceTime and iMessage activation and can be found here http://support.apple.com/kb/ts4268. It should help you resolve any issues with getting FaceTime and iMessage activated.
All the very best,
Sterling

Is there a fix for the iTunes push notification problem with Dropbox on iPhone ios 7.0.4

After updating to IOS 7.0.4 iPhone (which I now regret), when I open the Dropbox App, I get a warning "Connect to iTunes to use Push Notifications". When I push OK, it pops up again, constantly, so I can't even close Dropbox. Is there a fix for this? I've uninstalled and re-instaled Dropbox and checked for updates, but nothing helps. Any ideas?

Hello CraigNicholson
You would need to sync with iTunes to get that process to work for you. Check out the article below for more information on how to resolve that issue to get the proper token to use Push Notifications again.

USB tether using wifi connection on Iphone

I've been doing USB tether with iphone connecting to home wifi so that the data transfer using wifi to save my data plan for over 2 years and now it is gone with just with a network reset on iphone yesterday. I've done network reset for few times previously but it didn't effect the way of data transfer using home wifi on iphone while USB tethering. Any idea why is this happened and why the network reset of iOS 7.0.3 changed the priority of the wifi towards 3G?
