To spur development, Google now offers developers in 18 countries T-Mobile G1s for use anywhere. Proving that it is not as interested in tightly controlling its products as some of its competitors, Google is rewarding developers by providing them with T-Mobile G1s that are both SIM- and hardware-unlocked. Being SIM-unlocked means you can avoid having to deal with T-Mobile’s service (which is certainly a bonus).Obviously, the G1 is compatible with Android 1.0, and the images of the device online show that it ships with geometrical graphics on the back that make it look like a celebrity phone. It’s listed on the Android Market site as an “Android DevPhone 1” and requires that you first register as an Android developer on the site, which requires a setup fee of $25.The smartphone itself is going to run you $399 (but ships for free in the United States), and there’s a limit of one per developer. Google is offering the device in 18 countries, with more on the way. So far the chosen ones are Australia, Austria, Canada, Finland, France, Hungary, Germany, Japan, India, Netherlands, Poland, Singapore, Spain, Sweden, Switzerland, Taiwan, and the United Kingdom.
