Since the LG VX-10000 is a CDMA phone, can i purchase an unlocked one and use it on the bell network?

Also, I was told that the Bell network is locked and can only be used with phones that are registered and locked in the Bell network? True or False?

I believe this is true.

Technically you should be able to use any CDMA phone on bell's network, however its up to them if they will actually activiate it... they usually don't like unlocked phones since they would rather sell you one.
