Launch2Net works indeed very easy. People are surprised that I can use skype even in the train via my mobil without taking it out my pocket.
As I don't have an internet connection in my house, I use Launch2Net daily. It often happens that after ten or twenty minutes the connetion drops. Launch2Net says there stilll is one, except it has a speed of 1byte. Ofcourse it is difficult to say if this is the softwares fault, the phone's or the network's fault.
As well, once in a while Launch2Net crashes for no clear reason.
For the rest I'm very happy with it, because it let me use the internet, even with the minor hickups.
