I don't know if this is cool to post or not... I mention an online retailer...
I have been looking to buy those Blackberry OEM stereo headphones for a while. They FINALLY came available on the Blackberry site but the $10 shipping is ridiculous (total $40). I had one of those stock alerts on file with MobileCity and I got an email saying they had the headsets. So, I ordered one today - $26 shipped.
I know there are other non-Blackberry headphones that people have said work. I couldn't find those earlier.
They may be available elsewhere now, I don't know. I just thought I'd say I found them! I found them!
(I don't actually have them yet!)
