AT&T has made sure that Sling Player doesnt work on 3G or EDGE simply because it doesnt want to choke its data bandwidth. But if you are on a jailbroken iPhone, you can easily change this settings in sling player and watch video over 3G.

Here is how to do it:

1. Open Cydia app from your jailbroken iPhone
2. Search for Tricker ThreeG app
3. Tap Confirm and Install Tricker ThreeG
4. You can now run Sling Player on 3G and EDGE.

Note that this trick works for other VOIP programs as well. “Tricker ThreeG” app uses MobileSubstrate Library  that tricks apps into thinking that they are on WiFi even though they are on 3G/EDGE/GPRS. In the default settings you can use Sling Player, Fring, Truphone and Skype over 3G or EDGE.

SlingPlayer app for iPhone will be available on the App Store on Wednesday morning, according to a Sling spokesman. Unfortunately, since the company advises a 3G connection preferred to enjoy Sling on the go, this version is only working with Wi-Fi connection.

uses an internet media bridge to stream TV or recorded video from a user’s home to any compatible device like mobile phone.

According to Wired.com:

Sling originally submitted its SlingPlayer app, the software had the ability to stream video over the iPhone’s 3G, EDGE and Wi-Fi connections. However, Apple required Sling to modify the app to work with Wi-Fi only, according to Sling.

It’s reported that a 3G-capable SlingPlayer for iPhone would violate AT&T’s terms of service and could potentially strain AT&T’s 3g network. But it’s a bit weird since other AT&T devices like the BlackBerry Bold supports a 3G-capable SlingPlayer app.

The SlingPlayer app will be available for $30 in the App Store between midnight and 6 a.m. ET Wednesday
