This is probably a stupid question, coming from a stupid noob. Is it possible to modify an apk. For instance, there are three different sms apps that I like and use. Is it possible to somehow combine the key features of each and make a single app that does it all? I like the lightweight and easy interface of ChompSMS, the customization of Handcent SMS, and the key feature of sending sms's at a scheduled date with FutureSMS2. Just wondering if this is possible/legal/frowned upon or what?
