Apple iPhone 4G, 4, HD???

Will it be called iPhone 4G or iPhone 4 or iPhone HD ... too much confusion or is this all a marketing gimmick?

With Gizmodo releasing picks of what it claims to be the next generation iPhone, there is too much hue and cry about everything one can think of.

- What will it be called?
- Will it be revealed at Apple WDC scheduled on 7th June 2010
- 5 megapixel camera?
- Micro SIM?
- Will it have firmware 4.0?

Net-net even if we are to believe that photos revealed by Gizmodo are that of next iPhone, is it all that big deal for one to get excited about?
