While the original Nexus One app launcher seems cool enough, people want something more, and Touch Wiz can deliver. In a recent mod by XDA member rolle3k, he makes this possible on all Nexus One without flashing a ROM. The mod simply changes the launcher to what Samsung calls its own, and you can swipe left and right to reveal more icons.
I’ve modified the launcher itself to work with Eclair/Froyo framework.jar so you no longer need root to make use of this awesome launcher.
Either put the APK file on the SDCard and install it with any file explorer or install it with adb.
Feel free to include this in your Themes/ROMs!
The device has a great start menu, but you can get the changes from the mod thread._________
