Might the next front in the cola wars consist of advertising campaigns aimed at convincing the public to pour a particular brand of soft drink into their cell phones?

It will if Chinese designer Daizi Zheng and Finnish electronics giant Nokia have their way. The two have teamed up to develop a biodegradable cell phone that runs on Coca-Cola.

Thirty years from now will every adult have cell phone shaped cancerous tumors around their ears?

Disturbingly, the answer to that question is: maybe.

Some government agencies, such as America’s Food and Drug Administration, say risk from cell phone radiation is minimal. Others, such as the UN’s World Health Organization, say that alarm bells would make for an appropriate ringtone. France has gone so far as to ban children from using cell phones specifically because kids are most susceptible to radiation.

The wisdom of French lawmakers aside, the truth is that no one really knows with certainty the effects years of cell phone radiation can have. Only after long term studies can there be conclusive answers. At which point it might be too late.

So what’s one to do?

The makers of MagicJack have, for years now, implored you in late-night infomercials to ditch your telephone company landland and use their product instead. Their device, about the size of a deck of playing cards, connects to a computer on one end and to a regular telephone on the other. With a MackJack thusly installed a user can place any phone call over an internet connection; calls to or within the U.S. are completely free.

(Or course, what MagicJack doesn’t tell you in their infomercials is that theirs isn’t the only internet telephony service. See our comparison of MagicJack, Skype and Vonage. Ooma also has a VoIP product that’s more expensive but otherwise superior to MagicJack’s).

Starting in the spring of 2010 MagicJack will be expanding their competitive sights to the cell phone companies. A new MagicJack device will allow users to use their mobiles to make and receive free calls.

This new MagicJack has received a great deal of press. The AP even ran an article titled MagicJack’s next act: disappearing cell phone fees.

But will the new MagicJack really let you ditch your cell phone company?

Spot Cool Stuff is fascinated by the ever expanding functionality companies are bringing to Twitter. Some hotels offer concierge services via Twitter. Some take-out restaurants allow customers to place orders via Twitter. And now at least one VoIP company, Jajah, is launching a service that places telephone calls via Twitter.

Here’s how Jajah’s Twitter calling works:

Color us cynical, but when we first heard of the cell phone made out of corn-based materials we figured that the product would be little more than a green gimmick. (Perhaps we are still haunted by memories of drinking cheap corn-made beer—”beer” that literally cost less than bottled water—while in college in Iowa. But ANYWAY . . .)

. . . then we tried out the Samsung Reclaim. Turns out, the phone much cooler and less, well, corny, than we had imagined.

A few months ago we pondered the question Is the Ooma worth your moola? Our answer, in short, was:

Yes.

The Ooma Core VoIP Phone System is a product that allows users to make virtually unlimited telephone calls to, or within, the United States for free. Ooma’s call quality rivaled that of competitors Skype and Vonage, and surpassed that of MagicJack. Since the Ooma operates independently of your computer, allows for 911 emergency dialing and works with any standard telephone, the system is perfect for people seeking a cheaper alternative to a landline. You can even transfer a current landline number to the Ooma.

Not content to rest on its laurels, Ooma has announced that it will soon launch an updated version of its VoIP product: the Ooma Telo.

Sleek-looking smartphones are multiplying like Tribbles these days. Yet, even through all the noise created by the likes of the iPhone 3GS and upcoming Palm Pre, the HTC Hero caught our attention. And not only because this phone journeyed from drawing board concept to availability on Amazon.co.uk in a remarkable short period of time. In terms of form and function, the HTC Hero is one of the best phones out there.

It’s features include:

In our recent review of MagicJack, Vonage and Skype one commenter asked why we excluded ooma from our comparison. Like those three VoIP services, ooma (yes, the company uses a lower case “o”) allows users ditch their telephone landline and make calls over the internet.

Our reason for the excluding ooma in the previous review? We didn’t have enough first hand experience of the product. Now we do. Here’s our review . . .
