Application compiled with PhoneGap fails to update, but can be re-installed
If you ever encounter problem, that you can’t update (on your mobile device) applicatation compiled with PhoneGap or PhoneGap Build, first what you should do, is to try to uninstall it and then perform fresh install.
If that succeed, any following updates should run without problems.
This is caused, by PhoneGap version change (either manually, if you’re building by-hand, or automatically, if you’re building using PhoneGap Build). This is one of documented bugs in PhoneGap and hasn’t been fixed as of writing this article.
