An aggressive TV ad campaign by Verizon Wireless is adding to the support building for a software package from Google Inc. that is shaping up to be the most formidable challenge yet to Apple Inc.'s iPhone.

The commercials for the "Droid" phone, being made by Motorola Inc., list features that the iPhone lacks, such as a physical keyboard and the ability to run applications simultaneously. It ends with the tag line "Everything iDon't. Droid does."

It's not the first ad from a wireless carrier to take aim at the iPhone's weaknesses. Notably, Sprint Nextel Corp.'s ads for the Samsung Instinct and the Palm Pre have compared these devices to the iPhone. But the Verizon ads come at a sensitive time for the iPhone. User frustration with the network of the sole U.S. iPhone carrier, AT&T Inc., is growing.

Verizon Wireless gets high marks for its network quality, but it has lacked a "smart" phone that can match the iPhone's ease of use and breadth of third-party applications. The touch-screen BlackBerry Storm, which launched last year, is the closest Verizon has come, but the first Storm got lukewarm reviews and was plagued by software problems.

The Droid will run Google's Android software, which is gathering momentum as a platform for a range of manufacturers, in contrast to the Apple-only model of the iPhone.

T-Mobile USA and Sprint already have Android phones. With Verizon, the largest U.S. carrier, now on board, the free software package becomes more attractive to software developers who want to reach the widest possible audience for their applications. A wealth of applications, in turn, helps attract customers to a phone.
