VoIP has been ushered onto the iPhone in quite a few incarnations, but we'd wager than none of 'em are as useful as iCall. Said application is currently in beta form, though a release isn't quite ready for the public at large. Put simply, it enables iPhones to switch from GSM to WiFi (when WiFi is nearby, of course) on-the-fly in order to save cell minutes and bypass the hassle of manually changing over. Interested? We thought you'd be -- hop on past the break to see a demonstrative video of the app in action, and keep a close eye on the read link for a sure-to-surface-soon download.

If you're inclined to go big and multi-room with audio and video, Sony has unveiled some distribution products for you at the Pacific Coast Builders Conference, with two sets of high-definition video distribution products -- one for new construction, and one using existing Cat5 cabling. The NHS-3040 rack system is for new homes, and combines various Sony products for a whole-house distribution network: a home theater, XM Radio tuner, Blu-ray player, 400-disc DVD changer, and 80GB music storage and management server, along with support for 13 different audio/video zones. The NHS-2040 model drops you down to six zones, while the NHS-1040 removes the changer as well. For existing wiring, Sony offers up the CAV-CVS12ES HD switching system, which uses a single Cat5e per zone to route your video into up to 12 zones, and supports eight 1080p-capable component inputs. The system supports IR and RS-232 control, and pairs up with Sony's CAV-M1000 line of audio distro systems. As long as you're wiring up your house anyway, why not throw in Sony's WS-ADP4 doorbell intercom adapter with electronic door release, so you don't have to bother the butler to open the door for you while you're both in the third-floor bedroom watching Desperate Housewives in HD.

Routing calls every which way has been going on forever (well, almost), and Hip-IP's Mobigater Pro doesn't differ a whole lot from other Skype-to-cellphone channelers that we've seen in the past. Essentially, the device seamlessly "transfers your Skype calls to your mobile phone without the use of SkypeOut credits," as it connects to your mobile via an internal SIM card. As predicted, it interfaces with your PC via plain ole USB, and users can not only ensure that they never miss an incoming Skype call, but they can phone up other Skype users around the globe just by using minutes from their mobile plan. The device can even redirect calls to five different handsets, but considering the £185.99 ($373) pricetag required for such a luxury, only the heaviest of yappers need apply. Click on through for a shot of the rear.
