Might be a questionable decision.  The N-Gage is getting slammed
pretty bad in reviews.  Not to mention most people say that making a
phone call on it results in the caller looking like they have a Taco
Grande glued to their ear...

Wait for N-Gage version 2.

I'm not sure about supporting it in case it needs to be repaired or upgraded
but certainly you can buy it already in many electronics and gaming shops to
activate it with either Fido or Rogers because the phone comes unlocked. In
any case, stores that sell this product have the obligation to honour its
warranty.

That being said, I also agree with the comment that when one makes a call
with it one looks kind of awkward because of its "taco" shape. So you really
have to like gaming and be used to wearing a headset if you plan to get this
device...
