Can`t get Facetime to work with My3G!

[Buckmaster]

I have bought and installed My3G apps on my and my wife`s Iphone 4, but can`t get Facetime to work. 5 bars and 3G, and get the My3G sign when I hit Facetime, but get message Facetime unavailable. I have tryed over and over at different areas. Facetime works fine when we are on wifi. Need so help on this.

Mine was doing this also. I did a restore as new and re jailbroke. Now all is working.
