Yes! Finally OpenMoko has made available their first "open standards" based mobile phone available to be bought online at: https://direct.openmoko.com/ (Warning: if you are using some latest version of browser like IE7 or FireFox 2, you will get a warning on the certificate validity of the HTTPS site. I hope OpenMoko fixes this issue soon!).
From the site:
"OpenMoko is a GNU / Linux based open software development platform. Developers have full access to OpenMoko source and they can tailor their implementations to underlying hardware platforms. "
The current developer edition (Neo Base 1973) is costing 300 USD. The advanced developer edition comes for 100 USD more (which contains tools and stuff to open up the mobile physically).
There is a consumer edition slated to be released in October this year.
I am hopeful of this device, but as of now don't simply have the money to buy this cool stuff :(
