How to create Add On Packages

 I have seen several applications that are free, but allow for add on
packages to be installed.

Gang Wars sells Respect Points
Mafia sells Favors
Dungeon Quest sells Gems

The central game is a free app, but you purchase these add on apps for
in-game benefit.

Has anyone purchased one of these add on apps?  What is the experience
like?  Do you have to leave the add on installed on your phone?

How does this work technically?  Do you think they set shared
preferences?  How would you handle the 24 hour uninstall rule?

I am considering releasing a free game with 10 levels, but offering a
full set of levels (say 25) as a separate paid app.  I'm looking for
the best way to accomplish this and thought the above might have some

Thanks for your time,

2. Feature Request:Google Voice, refresh/notification

I think it would be a good idea if 30 seconds, 1 or 2 minutes is added
to the refresh inbox option. Currently the smallest refresh time is 5
minutes and this is very inconvenient for people who are frequently
sending sms through google voice.  Manually refreshing is a hassle, as
well al receiving a txt 5 minutes late.
