GLOBAL – What should you be looking for in the specs of a modern camera phone? Has Web 3.0 already arrived in the form of mobile apps? Is a universal inbox for your phone on its way? And what’s been the impact of snowfall in the UK on mobile phone usage? The answers to all these and more in this week’s round-up of the posts we didn’t write from across the Web.

• Steve Litchfield examines the nitty-gritty details of modern phone cameras on All About Symbian, covering hot topics like exposed camera glass, Full Focus and how many megapixels you really need. Steve’s had an awful lot of experience using mobile phone cameras, so his conclusions are worth reading.
• Remember when everything was “Web 2.0”? Andreas Constantinou on Vision Mobile makes an argument for apps as the new Web 3.0, delivering greater immersion, contextual awareness and relevance than the Web has ever been able to.
• You know how mobile phone signals can cause interference on local speakers, leading to an annoying experience with things like conference call systems? There might be a quick and easy solution on the way in the form of the buzz killer card, as spotted on Daily Mobile.
• It’s been snowing in the UK this week. What’s the impact of that on mobile use? Well, according to Vodafone, MMS messaging is up 63 per cent, week-on-week, as people presumably sent proud snaps of their back garden creations. Calls were up 17 per cent and text-messaging 15 per cent, as we merrily cancelled all our appointments and made our excuses to the boss.
• Beta Labs have introduced Soundtrckr, a geosocial internet radio app. What’s that? We’ll be taking a closer look next week, but in the meantime, you might want to read the blog post.
• Nokia’s experimenting with a universal inbox. Most of us don’t care if the message is an email, a text or a tweet – it’s the content that counts. So why do we have to use three different programs? MIT’s Technology Review reports.
• And finally. Not mobile-related but interesting to anyone who reads blogs and forums: what motivates people to comment online? A study by the Warsaw University of Technology found that, “The active users are those characterized with negative emotions and they seem to be the key agents that sustain discussion in the thread”. (Via ReadWriteWeb) Obviously, though, that’s not true of readers here, eh?

So there we have it. We probably didn’t find your favourite post of the week, so let us know what it was in the comments for consideration next week.
