I like to call my proposed solution the PATRIOT phone. It will look like this. It will feature RSA cryptography that is all but impossible to break, with no back doors or key escrow. With the right marketing strategy, a satisfactory product, and reasonable price points, it shouldn't be difficult to put such devices in the hands of several thousands of users. At that point, the device becomes an impediment to large scale surveillance. If even 1% of network traffic were encrypted, it would be impossible to capture that volume of traffic for cryptanalysis -- there simply aren't enough supercomputers.
