SAN FRANCISCO, June 8 (Reuters) - Apple Inc (AAPL.O: Quote, Profile, Research) halved the price of its entry-level iPhone to $99 on Monday in a move that could widen the trendy device's mass-market appeal as competition for smartphones heats up.

The company also unveiled a new iPhone that takes videos and has voice features, matching offerings by rivals Palm (PALM.O: Quote, Profile, Research) and Research in Motion's (RIM.TO: Quote, Profile, Research) BlackBerry.

Analysts said sales could double for the lower-priced iPhone.

Chief Executive Steve Jobs, on medical leave since January, did not put in a much speculated-about appearance.

The next-generation iPhone 3GS -- the "S" stands for speed, double that of the original model -- goes on sale in the United States, Germany and other countries on June 19 for $199 to $299.
