iPhone OS 4.0 firmware Hands-On Review

This is my iPhone OS 4.0 firmware to review hands-on. I'm enjoying this new software, because the burden of new features including: multi-tasking, folders, e-unified, iBook, Game Center, and touch the video camera focusing. These are only six of the 100 new features in this software. The new iPhone OS 4.0 software is released to the public in the summer of 2010.
