You TUAW readers came up with a long list of features for a possible iPhone 4.0, and now it turns out you might not even have to wait too long for a new revision. A few overseas providers of the iPhone have hinted that a brand new version of the handset could be coming out as soon as April of this year. Possible features this time include a video chat function, a removable battery, dual-core processors, and a better screen and camera (possibly with a flash feature, as we've heard before). That sounds like a lot of wishful thinking to us (I doubt we'll ever see an iPhone with a removable battery -- if Apple wanted to do so, they'd have already done it), but if not, that would be a pretty darn popular smartphone, and it would definitely answer the recent challenge of Google's Nexus One.
But of course as always, rumors are rumors, so we won't believe it until we see Steve Jobs holding it on stage, and you shouldn't either. But sources have long said that 2010 will be a year in which we'll see a new iPhone, and while April (or early May) seems earlier than we thought, you never know.
