I have some problems with my php service. I use php for send Tile update and Toast update requests to MS Notification Service. After first request in response I have following headers: 

URL: <http://db3.notify.live.net/throttledthirdparty/01.00/AAHFGdPCYDOUSbbzeTpjKOMZAgAAAAADAQAAAAQUZm52OjIzOEQ2NDJDRkI5MEVFMEQ>

Array ( [X-SubscriptionStatus] => Active [X-NotificationStatus] => Received [X-DeviceConnectionStatus] => Connected )

```

But in my WP7 app I have nothing. When I try update tile again:

It seems that after first request my url was deleted.

I do not have any problems in my WP7 app because when I use WindowsService all works fine.

It seems that my problem similar to problem [question]: [Windows Phone 7 Push Notifications Not Showing Up On My Phone](https://stackoverflow.com/questions/5981525/windows-phone-7-push-notifications-not-showing-up-on-my-phone)
