Hey guys, I've updated the first post to include details of an app that I developed that you can install and use directly on your phone to calculate MD5 or SHA1 checksums of any file on your phone (that you have access to).
Anyway, check it out and let me know what you think and/or if you have any problems or questions. Be gentle, this is my first app developed for Android
Again, big props and thanks to jcase from XDA who let me view a sample project he developed with eclips3 and gave me some MD5 sum starter code to get me on my way. I would not have tried creating this without him being willing to help me out. He deserves lots of credit for not only helping me but all of the help he gives the Android community in general.
