Ok last post on 3GSM. Just wanted to mention some small tech firms that I discovered while walking around in Barcelona.

Cerkle: social networking site with a twist. This site is thought from the ground up as fully integrated internet and mobile with both .com and .mobi addresses. As other players such as MySpace or YouTube struggle to mobilise their user experience, this is an interesting approach. So far, the web side is quite poor but let's see how it develops

Shozu: applet that you download on your mobile phone and enable you to easily upload videos and pics online. Great technology as it runs on the background and let do other things on your phone. Also, some rather smart file compression ensures your phone bill does not suffer too much. It is already compatible with several social networking sites such as Flickr, YouTube, Blogger or Typepad and - leveraging RSS support - could be used with almost any site

Inka: Korean company that developed a solution to transfer DRMed files across platforms. For example, it will enable you to play a song purchased on iTunes (AAC protected) on Windows Media Player or SonicStage (and vice versa) while keeping all the copyright protection. Even though Steve Jobs and some European governments are starting to raise voices to kill DRM, I am sure it will still be around for a while, so such a solution - if properly implemented - can provide additional freedom and flexibility in how we use the music we bought online
