HTC G1 users may find the Android Marketplace flooded with new Android 1.5 apps very soon.  Google has recent made an Android 1.5 software developer kit available to programmers.  This kit gives them access to everything included in Android 1.5, including the faster browser and the new video support options.  Of course, this kit comes with a caveat: Google has stressed that some of these new features aren’t finalized yet and that the final developer kit won’t be released until the end of the month.  Basically, this early version of the kit is to give app developers some ideas as to what will be possible, but all apps should be developed using the final kit, not this one.
