Hey guys,
I have a old 6750 on bell mobility. Id love to change it for something smaller, but not due for an upgrade til next year.
If I bought a verizon or sprint BB on ebay, would it work?
Does it have to be unlocked?
It should work in theory, but not sure if anyone has done it.
Anyone do it?

Technically no, Bell might not provision anothers carriers IMEI on their network? That being said before my wifes company moved to Rogers they were Bell subscribers and she was using a Kyocera 7135 from the Alltel network purchased in the US "unlocked" (if there is such a thing for CDMA) and it worked just fine on the Bell network. I would contact Bell before you make your purchase...
