So I look at Verizon's Droids and other Android-powered deives, and they all look different! I see HTC's droids have a giant clock and weather just below it (the home screen), the Droid X is like a blank home screen with the android logo guy at the top for help... And LG's android looks like totally different from the other two, its just like the enV Touch's home screen, but with teh Android status bar at the top. So do manufacturers modify teh open-source Android OS to their liking? Or is it just different ways of customizing your home screen? like could I change the HTC Incredible's home screen to look like the Droid X's as shown on verizon's website?
