I doubt that the phone is a Motorola V3m since that model is a CDMA phone.

To get rid of the Rogers logo you'd need to have the software on
the phone replaced with unbranded software, which would give you
a Motorola "M" (or, if you want the Cingular splat instead, Cingular
software).  I don't personally know of anywhere in the US which does this,
but googling variants of "Razr unbranding" or "v3 unbranding" finds some
links.  You could also ask your Cingular dealer if they'd put Cingular
software on the phone, but I bet they'd prefer to sell you a new phone.

Most people just live with the logo the phone comes with; it isn't
easy to get rid of it, and cell phones don't last long enough to
make it worth while spending money on it.
