Crazy amounts of 3G handsets were not the only gadgets showed off at this year’s Mobile World Congress. NetIndex, Kaga Electronics and Runcom showed off their WiMAX-enabled portable VoIP phone. According to PR Newswire , the companies joined forces to develop a VoIP handset that used a 802.16e module, and aside from “realizing all-IP voice communication,” it also features a web browser and integrated WiFi. We do not know when this will be available, but we guess next year.

Southwest Airlines has announced they will begin to test in-flight Wi-Fi as of the summer of 2008. Just after JetBlue and American Airlines, announced that they are also testing in-flight Wi-Fi. The service is satellite-delivered and will be provided by Row 44, who claim to be the current leader in airborne broadband communication. The first part of the testing phase will be on only four planes and will allow passengers access to e-mail, music, shopping and virtual private networks.

Row 44 is also working with Alaska Airlines and Virgin America to provide in-flight Wi-Fi access. The exact date for testing on Southwest Airlines has not been announced.
