WCF service call using TAP pattern does not honor WCF binding timeout

I'm using Xamarin iOS and the silverlight 3 slsvcutil to generate WCF services for use in a mobile app. I then create a task based implementation using the Task.Factory.FromAsync so I can use async await against the service call. In making this call for a lengthy data transmission I'm getting a network timeout exception at 60 seconds even though the WCF binding is set to use 10 minutes, long, but safe. The code to create the Task is:

public Task<byte[]> SyncExAsyncT(int accountId, string accountUsername, byte[] syncData, System.DateTime lastSyncDateUtc, int appVersion, string deviceName, string misc, int modelVersion, string deviceToken)
{
    return Task<byte[]>.Factory.FromAsync((callback, asyncState) =>
        base.Channel.BeginSyncEx(accountId, accountUsername, syncData, lastSyncDateUtc, appVersion, deviceName, misc, modelVersion, deviceToken, callback, asyncState),
        base.Channel.EndSyncEx, null);
}

I call the method as expected using byte[] responseStream = await client.SyncExAsyncT

How can I control the timeout of this implementation such that I can avoid the network timeout at 60 seconds?
