Has anyone run into the problem where they install an application and
it works fine, but then when they uninstall it and reinstall it (all
from the phone), the application loses internet connectivity?

I've installed 3 different podcast downloaders (hubdog, smartfeed, and
another that I don't remember) on my Sprint Motorola Q. In each case,
I did something stupid (like told it to download 300MB of feeds to the
phone itself), which left the phone in an unusable state, requiring me
to shut it off and reboot. Once I did this, I uninstalled the
application and then reinstalled it. Once I do this, the network
functions of the software no longer work.

Anyone know what could be going on, and if it is possible to
completely wipe out the old installation of the software (something
better than the Settings->"Remove Programs" ), or have any hints?

Thanks!
