All blackberries have 1 year RIM manufacturing warranty even if it belongs to a different carrier. Imagine a situation when you purchased you blackberry through say AT&T and used their services for six month and then decided to switch carrier. After another months you are experiencing problems with your blackberry . You call to AT&T to fix it, but they tell you :Sorry, we cannot fix it for you because you are not our customer anymore. Where are you going to call next. My option was, of course RIM. The only problem was that my blackberry end up being refurbished (coz I was stupid enough to purchase it out of the box) and RIM told me that warranty has expired on this one. Or, to be precise this blackberry never had any warranty on their systems. I think the reason was was because it stolen from RIM warehouse.
***Never buy blackberry on Ebay when the ad says: New RIM Blackberry, but no original box and half of original accessories are missing.
