Google is now vending out unlocked T-Mobile G1 called the Android Dev1. This simply means that the HTC Dream-based gadget can be used not only with any other SIM cards but with any other Android operating system as well. Nice, isn’t it?

Android Dev1 will soon be available in USA, UK, Germany, Japan, India, Canada, France, Taiwan, Spain, Australia, Singapore, Switzerland, Netherlands, Austria, Sweden, Finland, Poland, and Hungary. It can be registered to Google Android Developers for only US$399, and a US$25 is to be charged for a right to be certified Android developer.
