It appears that the new June iPhone will be so improved that the
current models will be unsaleable. Also there is a small possibility
that the iPhone will appear on other networks like Verizon, Sprint,
Altel etc. after June 2009 in the USA. Apple will drop its
requirement for part of the carrier’s revenues making up for them
from other sources that are developing from this wildly popular
innovative cell phone, iPod and internet device.

"Industry sources told Times Online that the device will have a
"radically different" appearance to the current device, which has a
4.5 inch screen and slick, aluminium backing. Among the possibilities
are flip version, which would enable the screen to be larger, and a
sliding model with a regular qwerty keyboard - as opposed to a
touchscreen one."
