The Android Dev Phone 1, a completely unlocked G1, is available to “developers” for just $399 after a $25 setup fee. All you need to do is register as a developer at the Android Market and the phone is yours. Registration as a developer costs $25, but after that, you’ll be eligible for the cheap, unlocked phone.

The Android Dev Phone 1 is fully compatible with Android 1.0, and being able to swap out the SIM card breaks you free of T-Mobile’s service. It’ll also let you use custom Android builds that work with the freshly unlocked bootloader. You can even get free shipping and cool detailing on the back. Google warns that it’s not really meant for non-developers, but we’re sure that won’t stop you.

Pretty sweet no?
