Short answer is NO as Apple has restriction on background task running especially cases like yours.

But if you are downloading small amount of content, you do have some other options. From IOS 4.0 or above, you can declare your app to run in background when you fall under the following categories:

Audio
Location updates
Voice over IP
Newsstand downloads
External accessory communication
Bluetooth networking
Bluetooth data sharing
Background fetch (IOS 7)
Remote notifications (IOS 7)

In order to do so, you need to flag your app in the info.plist for Required Background Modes option. Apple will review your app specific in this area once you declared the option.

For your case to download the data, the possible option is to use the new feature in IOS 7 that's the background fetch or remote notification above. The suggestion from DOM was not asking you to download the content through push notification. But instead to use push notification to wake up your application and start downloading new content.

If you don't want to use push notification, the only way to go is register for background fetch. However, no matter which option you want to use, each download will only last for 30 seconds. And after that, your app will put into suspension mode again.

I think your best bet would be to use the push services instead of having your app go get data. Making your app do it is unreliable with phonegap apps because you cant create a service interface and you can not guarantee that your app will be running. With push service though, if your app isn't running, it will be woken up in a manner of speaking.

Take a look at this great how-to article that also discusses what push provides you.
