Want to use SlingPlayer on 3G and not just on Wi-fi? Then Tricker3G should be the trick for you.
Tricker3G is here to trick the recently released SlingPlayer app that it is on wifi, but in actuality it is on 3G. The same can be said about Skype with this tweak. Now I couldn’t try out SlingPlayer as I do not own a Slingbox but I did test out Skype and it worked just as good as VoIPOver3G. Making a Skype call over 3G worked fine, as far as quality goes, that’s really dependent on the network, not the Tricker3G. But if you want to use either Skype or SlingPlayer over 3G and literally anywhere, give Tricker3G a try.
