If you want a phone that runs Openmoko you can either buy the Neo FreeRunner or you can install Openmoko on a supported device. Note that much of the software is still under development and not suited for regular users yet. For learning about what you can and cannot do with the current types of software please see distributions.
Buying Neo FreeRunner
You can purchase the FreeRunner from the Openmoko store or from a local distributor. At the Openmoko store the FreeRunner costs US$399. It has a limited warranty for 14 days. If you want an extended warranty you should buy from a distributor.
Some distributors, including the official Openmoko store, are selling packs of 10 phones for a reduced price. At the Openmoko store, the price is US$369 per phone. You may want to join a group sale with people in your area.
Installing Openmoko on your mobile
You can also install Openmoko on other mobile phones. For a list of phones on which you can run Openmoko please see supported devices. These devices will likely not fully support Openmoko and may not offer any GSM functionality under Openmoko. Currently this wiki doesn't provide any information on installing Openmoko on other devices. If you have some, please share it.
