Thanks for the reply.
I use wireles tether with no problem on upto 5 devices. My question is whenever I try to make call on skype, I get a msg saying in united states you can make skype calls only over wi-fi. Can I dupe my phone into thinking that I am using wifi instead of 3g by using my own tether as wifi. I hope I make sense now. I haven't been able to do it so far
