I have a 32k sim that has 2 lines on it. (Personal and Business lines). I never had any kind of delay when activating either sim as the phone will just automatically turn off and on to switch between lines. With the Centro, its sometimes as fast as my 680. Most of the time, its delayed to as much as a minute plus. With this kind of delay, its no longer convenient switching between line 1 and 2.

Has anyone experienced this?
