Google Inc. has acquired reMail, which develops e-mail search applications for smart phones, and promptly shut it down for Apple Inc.’s popular iPhone.
The move likely marks another skirmish in the escalating war between the two Silicon Valley giants.
Google of Mountain View hasn’t discussed the purchase publicly — and no one’s disclosed the price — but ReMail revealed the purchase and decision to discontinue the iPhone app on its blog.
Odds are that Google intends to reserve the technology for smart phones running on its own Android operating system.
Apple, for its part, has pulled applications from its App store that enable Google Voice, the company’s call forwarding service.
The two companies recently enjoyed a cooperative relationship, sharing several board members, but have increasingly found themselves at odds as each moves onto the other’s turf.
Earlier this year, Google started selling its own smart phone, the Nexus One, which some dubbed an iPhone killer. On the same day, Apple barged into Google’s online advertising stronghold by picking up mobile ad company Quattro Wireless.
