How to Use SlingPlayer Over 3G

Since the release of the SlingPlayer iPhone app in the App Store yesterday, there’s been much noise about AT&T’s restriction that makes the app operational over wifi only. But as usual, the jailbreak community is here to save the day! If you haven’t jailbroken your iPhone yet, here is reason #1,563,982 to do it…

Thanks to VoIPover3G, you will now be able to use the SlingPlayer app over 3G and Edge. VoIPover3G can trick any application into thinking that it is on Wifi even though it is on a cellular data connection. You can configure what apps get tricked by adding the app’s bundle identifier to “/Library/MobileSubstrate/DynamicLibraries/VoIPover3G.plist”.

In order to use this simple hack, your iPhone must be jailbroken, and you must install Mobile Substrate, OpenSSH and VoIPover3G (reboot after install) from Cydia.

Assuming you’ve installed these apps and that you know how to SSH into your iPhone, follow these instructions:

1. SSH into your iPhone and go to the root directory “/”

2. Navigate to /Library/MobileSubstrate/DynamicLibraries

3. With a text editor, open VoIPover3G.plist

4. Look for:

Filter    =        {Bundles     =      (”com.Fringland.Fring”,       “com.apple.AppStore”, “com.audiofile.Interstate”, “com.apple.MobileStore”);};

Now add this part: , “com.slingmedia.SlingPlayer”

It should look like this:

Filter = {Bundles = (”com.Fringland.Fring”, “com.apple.AppStore”, “com.audiofile.Interstate”, “com.apple.MobileStore”, “com.slingmedia.SlingPlayer”);};

Don’t forget the “,” and the quotation marks!

5. Save the changes you just made and upload the file back to its location: /Library/MobileSubstrate/DynamicLibraries

6. Reboot your iPhone

7. Done! SlingPlayer should now work over 3G!

There is also an easier way to get SlingPlayer to work over 3G… Simply launch Cydia and look for the Tricker ThreeG application. It does the exact same thing as the above hack except it tricks ALL apps to think they are on wifi. It’s much simpler than SSHing into your iPhone but remember that by installing Tricker ThreeG, all apps will behave like they are on wifi. This is not recommended because for a lot of apps its makes sense to know whether they are on wifi or 3G.
