OpenMoko has just announced the Phase 1 release of their new open source phone.  Not only does the new phone have a giant touch screen display similar to the Iphone, but it runs a full fledged Linux kernel.  Oh, and at only $300 (for this developers release), it looks to be even cheaper than the Apple alternative.  What makes this phone so unique is that it's the first phone ever released to be 100% open source.  Not only have they released their source code though, they have also designed the phone from the ground up to be flexible and open.  Show me one other manufacturer who not only allows you to open the case of the phone, but ENCOURAGES it (here's a quote from their site):

Others try their best to lock us out of the devices we buy; but, Neo’s are built for you to open. You can take the casing apart and get at the PCB. Opt for the Neo Advanced kit and we’ll give you a special screwdriver, (the Neo cracker), and plastic guitar pick to make opening this device even easier. Go ahead, open your Neo. Make our day.
