Has anyone had any trouble (or heard of people having trouble) with iLiberty? My iphone arrives tomorrow and I was all ready to to use ziphone to unlock it being that for months people have been saying that it is the best thing out there. I blinked my eyes for a second and now everyone is saying how horrible it is and how much better iLiberty is, etc, etc. Being that everyone I know used ziphone, I am a little nervous to use iLiberty. Any advice?
