Kyocera 6035

The Kyocera 6035 was one of the first smartphones to appear in the American market.

Its predecessor was built by QUALCOMM and called the PDQ 800 (and 1900), then after Kyocera acquired Qualcomm's handset division (Qualcomm Personal Electronics), they built the QCP 6035. It was one of the first phones to combine a PDA with a mobile phone.

The phone appears to have a dual-software nature, with the cellphone firmware operating independently (though available through an interface) from the Palm OS system. Like most modern smartphones, the phone operations can be off while the Palm operates, and vice versa. The systems are sufficiently integrated to pass important messages and commands to each other, though the phone's operating parameters (settings, phone book, speed and voice dial, call history etc.) are configured via the Palm OS system.

The phone has physical buttons for cellphone use, arranged on a flip which covers the Palm buttons, Graffiti area, and part of the screen. The upper part of the screen shows the phone system display when the flip is closed; when the flip is open the screen switches to Palm operation. With the flip closed, phone operations are performed via the flip buttons and a side thumb wheel.

The Palm OS system benefits from the integrated cell phone by utilizing it as an attached modem. This allows the Palm to take advantage of any IP-based Palm applications, such as email clients and web browsers. The phone can also be used as an external modem for a computer via the HotSync cradle.

The phone can receive SMS messages, but earlier firmware revisions did not come with a mechanism to send them. It is WAP capable, but not MMS capable.

The 6035 comes with 8 MB of Palm memory and is not expandable. It can perform HotSync and IR communication just as a normal Palm.

Different versions of the phone were made available for different CDMA wireless networks. (It was never made for GSM).

The successor to the 6035 was the Kyocera 7135.
