If you happen to own an Iconia Tab A100 and want to try this mod, it’s highly recommended by crossix that you back up your original in case anything goes wrong, but otherwise the mod is pretty powerful and simple to use. It is a list of changes that the user can to the build.prop in order to improve performance and functionality. Crossix explains:
Your build.prop file contains a lot of information about your tab. Things like what model, version of android, manufacturer and other info can be found within, but it also can control certain aspects such as display density, wifi scan time and other misc tweaks that improve overall smoothness.
The mods are all changes made to the single file, so there’s no need to flash or adb push anything. Simply grab the modified build.prop, place it where your current build.prop is and you’re done. Changes made range anywhere from the name of the device to the Iconia A500 so you can get apps in the Market intended for only the A500 to a range of tweaks to improve system performance.
For a list of all the changes made, the download link to the modded build.prop and additional disclaimers you can find all that and more in the original thread.
