I stumbled upon this solution when looking for a way to get rid the background on Flick Note‘s widget, making it text only–perfect for fitting into the text-only look that so many users like. You can do any kind of tweak you want; all you need is a photo editor and the Android SDK. It’s much easier than it sounds, too; I was able to get my new, edited widget up and running in less than 10 minutes.
Hit the link below and check out the video above for step-by-step instructions. You don’t need to be rooted to do this, but if you are rooted, you can skip the Android SDK altogether and just copy the APK file to your SD card using Root Explorer. Also note that if you’re editing an app with a “Pro Key” available in the Market, you’ll need to re-sign both APK’s as described in the video, or else the Pro key won’t be recognised.
