I bought mine from amazon so I was counting on them to back me up if I got a defective unit out of the box. As far as warranty, I've been around the Sony forums for a couple years now and honestly I wouldn't expect much support from Sony even if the phone was in the region where they sell it. I've read of a lot of people having bad experiences with Sony support. If you're using a credit card to buy, they might offer some assistance. I know my cc gives me an additional year of warranty after mfg warranty expires plus a 90 day accidental damage protection.
