Tricking apps to believe your in different region?

[popasmurfn25]

I have bbc player but you can only stream the vids if your from UK so i was wondering if you can work around that if you live in the USA. Example you can trick the market into thinking your an att phone instead of sprint phone. You can do this by installing the app called marketenabler(need to be rooted). Now is there a way to do this with apps?? Make the app think your on a UK server, either before the app is selected(manually) or (auto)with a pop up screen when the app(bbcplayer)is selected?????
