release some form of a server-side optimized browser such as Bolt? IMHO (and many others), the BlackBerry browser is sturdy and reliable, but outdated.
No popular smartphone manufacturer that I can think of (and I could be wrong) has a server-side optimized browser by default. This could be a big selling point, and also takes up less bandwidth. Less bandwidth is good for the carriers, who should step up and insist such features from handset manufacturers.
