TrollTech announced an ‘open’ phone, called the Greenphone. It runs Linux (QTopia Phone Edition specifically)

It is a full-featured GPRS/GSM phone:

• dual-core 312MHz XScale processor
• 64MB Ram, and a mini-SD flash slot
• 1.3 megapixel camera
• Bluetooth
• WiFi networking

Looking at the success Nokia has had with exposing various developer interfaces to their mobile phones and N770 tablet (Maemo), I think there is a huge market for an “openphone”. When I first heard of the O’Reilly Telephony Conference, I pictured people sitting around with their antiquated telephones, talking about switchboards and the like. I guess it’s a lot cooler scene than that.

Additionally, hopefully Open-hardware like mobile phones and tablets will kick the closed-minded carriers into realizing they’re slowly strangling themselves by keeping everything closed and begin to work with the huge, untapped, hobbyist and developer community.
