What is VoIP? Voice over Internet Protocol (VoIP) is the ability to transmit voice over the Internet to either a receiving computer, telephone or even a mobile phone. VoIP phone is becoming the popular worldwide telephone service for both consumer and the business communities. VoIP works by using a network technology known as Packet Switching Network whereas landline telephones use the Circuit Switching Network. This is referred to as the Public Switched Telephone Network.

What's the difference between VoIP normal phones?

The main difference between Packet Switching and Circuit Switching, is that Packet Switching uses (data) or Packets and sends them over the Internet while Circuit Switching is accomplished by using electrical circuits to make a telephone connection. Circuit Switching is like the old switchboard operators, frantically trying to connect the right caller with the receiver. Packet Switching is used to transfer data all across the Internet including E-mail. Packet Switching converts audio formats into data packets and transmits them over the Internet, then reassembles them on the other person’s phone or computer in real time. By using a Broadband Internet Connection, microphone and speakers a conversation can take place similar to traditional telephone.

It's PocketPC playoffs and HTC are giving Samsung a match at the GSM Arena. With two of the stars of the season arriving in our office all at once, we thought it's a heck of an opportunity for some Diamond-Omnia-Diamond-Omnia-Diamond-Omnia game-set-match with a pinch of iPhone flavor. We got two aces up to the challenge, so sit back and stretch out. Ah well, get that six-pack too and join us for the kick-off.

Samsung i900 Omnia and HTC Touch Diamond might differ here and there in specs but no doubt we're talking fine top-of-the-shelf species. Never before have Windows Mobile powered devices been so rich in features without being coyote-ugly (another way of saying TyTN-bulky).

It's been a year now since Apple iPhone is out and its ground-breaking user interface took the industry by a storm. Windows Mobile however still fails to pick up the gauntlet thrown by the iPhone so device manufacturers are creating their own customized touch interfaces that don't necessarily require a stylus to make the Microsoft OS a bit more competitive and much more intuitive.

It took almost a year to see all manufacturers introduce their solutions. With the HTC Touch Diamond we are looking at the third generation TouchFLO UI - a really mature and impressive piece of software. The Omnia and its TouchWiz UI is Samsung's first attempt in this field, but they're building on their expertise in full touchscreen feature phones and they have achieved some impressive results too.

So you already probably guess that we will be spicing up today's Windows Mobile competition with a few Apple iPhone quotes. With the iPhone 3G just behind the corner, we think that several key generic comparisons might be of use to most of you. But for starters, check out some photos of the contenders lining up for the Windows Mobile cup. Slick, aye?

HTC Touch Diamond

Samsung i900 Omnia

Before we begin today's match, we should warn you about the units we are testing. The Samsung i900 Omnia is still a beta version, while the HTC Touch Diamond is a retail unit. However, dozens of bugs are being reported for the Diamond recently, so it isn't actually as stable as it should be. In fact, HTC are struggling to polish the Diamond performance, which - even though utterly impressive - is rather unfinished at its launch. Looks like HTC made haste to beat the iPhone 3G announcement.
