basic apps questions for LG 840G
I have a couple of rookie questions about apps for the LG 840G. (never used an apps-capable phone before)
What is the difference between a signed app and an unsigned app? Is it just a matter of granting permission to access the web each time it’s used, or is there more to it than that?
I installed Google maps v.2.3.2, but it gives a fatal error in the middle of starting up. Does this just mean I got a bad copy of it, or is there something else I need to install along with the jar file to make it work? Also, is there a more recent version of Google maps?
