Apple's legal department may have a busy holiday season ahead of it.

The Cupertino, Calif.-based iPhone maker is facing two new lawsuits stemming from its popular smartphone -- a patent infringement claim tied to the iPhone's Web browser, and a second suit that claims the iPhone 3G is not delivering on Apple's promised capabilities.

Both suits follow litigation filed earlier this year that charged that Apple misled consumers about the high speed and other features available to users of its iPhone 3G.

The patent infringement suit, reported yesterday by Reuters, claims that Apple used Web browser technology under patent by Elliot Gottfurcht and two co-inventors.

The second suit was filed Nov. 19 by an iPhone 3G user from San Diego, Calif., and seeks $5 million in restitution from Apple. In the suit, plaintiff Peter Keller claimed the iPhone 3G suffers from poor performance and sluggish network speed, and that Apple breached its warranty of service and had falsely advertised the smartphone's capabilities.
