Along the same lines as this question. What's so special about enabling Unknown Sources, and what are some things that I should do once it's enabled?

I'd upvote but I ran out of votes last night... check back in ~6 hours. – gary Jan 27 '11 at 16:24

This allows you to obtain and run an application (i.e. the .apk file) from sources other than the Android Market. (i.e. you get it from a download from a developer's site, from an email, etc.). That's it.

Edit: Once you enable Unknown Sources this post covers the rest: How can I install an app given only its APK file?.

For example, enabling Unknown Sources allowed me to install the Beta version of the Swype keyboard from (but if your phone already has Swype then don't do that) – Luke Dunstan Jan 27 '11 at 16:23
Ah cool. I had always seen "enabling unknown sources" listed as a thing to do after rooting, but never saw an explanation why. – travis Jan 27 '11 at 16:28
I don't have "Unknown sources" on my Dell Streak. What should I do to get this option??? Please, help! – Pavel Popov Apr 11 '11 at 15:44
@Pavel: You must have AT&T as your carrier. AT&T has (in)famously disabled the "Unknown Sources" option. Unless you're willing to root your phone and install a custom ROM, you're out of luck. – Al E. Apr 11 '11 at 15:50

Visit and go nuts! download cranky birds. It seems to be the game so many people like.

I wonder if there is an android version of Cut the Rope out yet.
