How easy or difficult would it be to get the stock Android messaging app (like on the Nexus One) and modify the apk so that it will install on an UNROOTED Droid Eris? Because if you download the stock messaging apk, it won't install because it is basically named the same thing as my HTC messaging app that comes stock. So if Handcent and all installs as seperate messaging apps, is there a way to make the stock Android messaging different so that it will install? If I can modify the Handcent apk, resign, and install it successfully, shouldn't there be a way to modify the stock Android messaging app and install it without root?
