Decision to design similar to iPod touch instead of using glass is supposed that Apple seems to stop problems which are told widely damages from scratching, difficulties of painting white and weight of glass.
The source also reported that Apple is abandoning the current external antenna design that was plagued with controversy over the â€œdeath-gripâ€ signal loss and attenuation issue.

Finally the source noted that Apple will include the new A5 processor in the fifth iteration of the iPhone, the same processor in the new iPad 2.

In particular when the source has a shaky record in previously predicting a 7-inch iPad by Christmas 2010. [Via MacRumors]
