From Wikipedia
The Android Dev Phone (ADP) was a series of SIM-unlocked and bootloader unlocked Android devices designed for advanced developers. While developers can use regular consumer devices purchased at retail to test and use their apps, some developers may choose not to use a retail device, preferring an unlocked or no-contract device.
