This new build pushes the Streak 7 up to Android 3.2, thanks to some files from the Motorola Xoom's Honeycomb ROM. He has also fixed some other various SD card storage mount issues and changed the stock LCD density to 120px.
One outstanding issue in the new build is that mounting the SD card via USB is broken, though you can still transfer files over WiFi or mobile data using various data transfer apps like Dropbox or Gmail. Another bug involves two-way video chatting over Google Talk: if you try to video chat with someone, they can hear you, but you can't hear them.
