PALM Desert, California - In September last year at DemoFall, I wrote that the most obvious trend in evidence at the confab was a technology demonstration of the prevalence of iPhone Apps. It seems that at least several dozen of the 72 companies that show, put at least part of their product offering for Apple to hit the device.

Here, in the demo-09, I realized that this ratio will jump, or at least, remain roughly the same. But increasingly, this time - only 39 companies have submitted, for example, as are hundreds of smaller parties - and how can I say, iPhone is hardly a hot platform.

But there are a number of companies that have applied to the iPhone - or other wireless devices - in their proposals. And indeed, some of them were clustered in the afternoon session, entitled “iLove my iPhone”. But despite that title, only a few are really focused on the iPhone Apps.

Nevertheless, companies are grouped in this session - Coveroo, Promptu Systems, HAM-IT, Asurion Mobile Applications, bluBuzz and Skout - there is a very interesting technology and services occurs. How many of them will be the last, of course, is unknown, but it is no different from any other product category in the demo, or other business technologies.

Perhaps the most interesting of these applications, Asurion Mobile AddressBook, in fact, are not available (yet) for the iPhone. Currently, it is only in the Android. As users of iPhone, although I can still appreciate Android Apps, especially those that are smart and provide some new functionality.

Mobile AddressBook this cool app that brings many fresh context, balanced list of names and phone numbers with which we are all so familiar. Now Android users will be able to establish direct links with numerous photos Flickr, Facebook pages and chirrup of these channels in their contact lists.

It’s quite cool - an opportunity to go directly from the address book, say, a friend of Flickr photos. But even better, that Asurion is the provision of open API, which will allow third-party developers to link other social tools to the list of contacts. This can be almost anything you can imagine. In addition, there will be so-called “smart contacts for companies such as airlines. So, you could have a south-west Airlines to your contact list, and click the direct route from there to see the upcoming routes or your account.

Of course, Palm pre-built around the same functionality - but, as the Android app, and perhaps later in the iPhone, someone that provides these functions without devoting a new Palm phone.

Another very interesting application on display Skout, social and dating service for multiple platforms, including iPhone.

Skout requires user registration, but if they do, those with a compatible phone - the service requires a GPS - will be able to see other members who are somewhere nearby. And for every person who appears, you can see how far they and their profile, and add them to your friends list.

Skout in the iPhone application that allows people to flirt with any other user services that are nearby. It uses GPS, to determine who is next, and social networking functions that combine well with more traditional instruments dating services.

Does it really help to find love no one knows, but the idea is interesting. There certainly was a lot of mobile social applications in the past - remember Dodgeball? But to make this choice in a system combining GPS and is fast becoming perhaps the most advanced of such app I’ve ever heard.

The next notable iPhone app was Promptu Systems’ ShoutOut, voice to SMS-system platforms. It’s very simple - this is exactly what it sounds like: it converts spoken words into text, which can then be sent as a text message.

You may ask why you want to use such a system, and then think about how often you can send someone a text message while driving, and how to do this can be unsafe. In this case, you can simply hold iPhone to mouth, for example, that you want to say and then ShoutOut technology to convert your words into text, which you can change, if necessary, and then send.

I wonder how popular it would be, but given how dangerous it is to text and drive, I hope that something like this will become popular because there is very little chance that the drivers are going to stop trying to communicate just because they are behind the wheel .

And, ShoutOut doing the same voice to text translation on twitter, which means that you can send a tweet from your iPhone without type in.

A much more physical changes in your mobile device Coveroo for laser-etching service.

That’s exactly what it sounds like: a system that allows you to have the image etched on the back of the device, be it iPhone, BlackBerry, IPod, or one of the dozens of others. The company has a collection of more than 200 licensed images - from, say, “The Simpsons”, - and it also can work with any custom image sent to it.

I already wrote about the laser etching services, as consumers, facing the business, it started with Adafruit Laser Services, New York that the company will Etch any laptop, IPod, or cell phone. And in many ways that Coveroo does not so much different.

In addition to the sale of personalized mobile phones include, Coveroo soon propose ordering engraved laptops as well.

But in some respects it is. In particular, licensed images Coveroo provides opportunities to attract customers with the very popular movie or TV show characters. In addition, the company also hopes to license its technology to retailers in the hope that places like Best Buy or mobile phone will offer retail services to customers etching rights when they buy their appliances.

In addition, Coveroo serves as a mediator in some of the devices in the sense that customers can order a new phone, it is etched, and then sent them.

At $ 10 to $ 50, it seems reasonably priced (especially at the lower end of) a way to personalize mobile devices, or even protect it from theft.

A couple of mobile applications on display here at the demo I’m not so sure are bluBuzz in Bluetooth ad platform, and HAM-IT’s own client and service provider, the relevant service.

BluBuzz built a system that allows companies to reach the mobile device owners with instant suggestions - via Bluetooth. The idea is that for those who signed with the service, a special offer of a business is just ping. Location aware technology can extinguish a signal that travel up to 1000 feet. Thus, if, say, an ice cream shop has a special flavor today, it could push the announcement to anyone in the area who have signed up for BluBuzz - which would then be a proposal on their device.

This is an interesting idea, but I’m not sure how many people will sign up. In addition, I can imagine it being somewhat annoying to have invited the popping on my phone from time to time, but the company promises that it will be unintrusive. Nevertheless, I remain skeptical.

Finally, Ham-It has built a system that coincides with the suppliers of services to clients who are looking for specific services. He basically is not a mobile application, but have a mobile component that would allow someone in, say, iPhone, not to mention looking for an accountant in Boston, as well as any accountants in the city who uses the HAM-IT offers up their own business.

This, apparently, as the services that few people will use in their devices, and I can not see him succeed. It may be better on the Internet, but the emphasis on the mobile side of things, it seems less important to me.
