We all know that a new iPhone is soon going to be available. Our buddies from Engadget managed to get some info from a very authoritatively source about the next-gen iPhone so here it is.

• 3G and GPS are the main changes. Lots of people screamed for those features and Apple listened very carefully.
• The new iPhone is going to be all (glossy) black, it doesn’t have a back metal case anymore and should be slightly thicker.
• Apple may start shipping it from July.

Though these are pretty interesting changes, there is still no word on a removable battery but I guess you know that when we talk about Apple, nothing is final. The source seems to be highly credible but even so, take some salt with it.
