Ok, here's my situation: I made a custom themed, modified version of ADW.Launcher 1.0.1, as I have with previous versions. They will not install via a file browser & package manager on the phone or using adb. The only way I've gotten them to install is by flashing it to /system/app/, but that makes future updates impossible unless I restore my phone to an earlier state. My question: How can I simply make this install or how can I theme an application already installed to /data/app/? I suppose signing it myself could work, but I'd have to learn how to do that. Thanks!
