SAN FRANCISCO: Apple Inc's new iPhone goes on sale on Friday with a bigger screen and 4G wireless technology, as the company seeks to safeguard its edge over rivals like Samsung Electronics Co Ltd and Google Inc.
The iPhone 5 fulfilled many of the expectations laid out by gadget geeks and technology analysts ahead of its Wednesday unveiling but offered few surprises to give Apple shares - already near record highs - another major kick.
