How-to Hack Samsung
The Samsung Galaxy S i9000 is the bees knees in Android phone offerings with its 1GHz processor and souped up GPU for super-fast video handling. (Check out my video showing off the i9000’s Live Wallpapers hacked onto a Nexus One.)
Following that thread, rolle3k on XDA-Developers.com has ported the Samsung TouchWiz launcher from the i9000 to the Nexus One.
There are couple pre-requisites: you must be running the FRF83 Froyo build, and you must have root access.
Once you’ve met those requirements, download and install the “TouchWiz package” (touchwiz-signed.zip) and place it on the root of your sdcard.
Next, reboot into Recovery Mode, and use the Flash Zip from SD option to apply the touchwiz-signed.zip update, then reboot after the update is complete. Be patient, your first boot will take a bit longer than usual while ODEXing taxes place.
The developer notes that there are still issues with “Apps and the Widgets” that he’s working through, but for those of you who want to try out the TouchWiz UI, this is a relatively easy way to do it.
