Hi friends, my experience shows that generally, when a manufacturer takes a model number of phone and spanks an additional letter after it, there’s some kind of feature or revise they’re giving importance.
iPhone 3GS? That one’s simple: “speed.” But if we’re watching this FCC business carefully, Nokia’s latest 5800i XpressMusic phone apparently differs little with its older model, only for the actuality that they’ve removed that irritating WiFi antenna from the handset. Because, actually, what would you do by means of all that connectivity, anyhow? Also, while still providing a 3 megapixel camera, those specifications are given as a 4.6mm on the new gadget (the original is 3.7mm).
As a site has pointed out, that this could be because of either a narrower area of view or a bigger sensor — probably the second one.
