One of the last big secrets about the new iPhone 2010 is its final name. In the iPhone rumor land the most used name is iPhone 4G. 4G has though a double meaning and will not be the final name Apple will give the new iPhone.
iPhone HD has potential as the new iPhone will have a huge resolution.
Ideal Case is teasing (via MacRumors) cases for the new iPhone referring to it as iPhone 4GS. Apple unveiled the 3GS last year and the S stands for speed. The new iPhone 2010 is expected to be again faster. It has some merit that Apple sticks with the S also for the new iPhone.
The official unveiling of the new iPhone is already very near. Steve Jobs is expected to pull it out of his pant pocket on June 7th at the WWDC 2010 keynote.
