Apple recently announced that it has officially received FCC approval to sell the iPhone, its much anticipated entry into the mobile phone market. Along with getting FCC approval, the iPhone is ready to ship next month, Apple spokespeople said.

All mobile phones offered in the United States must receive a "grant of equipment authorization," which means it has received the green light from the FCC.

"We're on track to release it in late June," Cingular spokesman Mark Siegel said. "Nothing has changed."

FCC documents confirmed the iPhone will have WiFi and Bluetooth capabilities. Apple requested the FCC keep several details secret from the public, including the official launch date of the device. Apple also requested the FCC not release external or internal photographs and user manual of the iPhone for 45 days -- which means the material will likely not be made available until the iPhone is on the market.
