Gdgt reported a rumor that Sony is working on a digital camera with integrated 3G connection. This will not be another smart phone, but rather a Cybershot camera that will allow instant upload of images online via an integrated 3G connection. Sony already has a Cybershot phone in Japan and such camera will not require a lot of R&D:
Panasonic also has a "Lumix Phone" that was announced in October of 2010.
Eye-Fi is also working on an iPhone app that will allow you exactly the same thing - upload images from your camera online. The connection will be established via the Eye-Fi card in your camera and the iPhone app. See my Eye-Fi Pro X2 8GB SDHC memory card review for more details.
