Apple, if you are listening, here's a product idea; It would be fantastic if it was somehow possible to combine the iPod touch technology with that of a mobile phone. Just imagine the possibilities; From one device you could call your friends, do SMS, maybe even browse the web using some kind of always-on wireless connection (might not be possible today but surely some time in the future). To illustrate the concept, I have created a simple mockup. Hope this will be possible some day.
