One of the really stellar decisions of AT&T was to block the Dell Streak from loading any app that didn’t come from the ‘authorized’ Android Market. That means that if you want to load a beta of an app (Audible, Touchdown, etc.), it is not possible. Even the normal Settings toggle to allow this is absent. One way to get around this is to ‘root’ the device (get root access). However, if you aren’t prepared to do that, the method outlined below will get you there without needing root access.
Just the Steps
- Dial *#*#307#*#* on your Streak. Other than a quick flash on the screen, it will look like nothing has happened.
- Go to your app drawer/program menu and tap a new icon labeled EMList. If the icon is not there, turn off the Streak. It should be there when you turn it on again.
- Scroll to the bottom and tap app_security.
- Tap update unknown resource property to enable it.
Now, simply tap the Home button, press Menu, and go to Settings > Applications, where the “Unknown Sources” check box is now available. That’s all there is to it! If you ever want to reverse this, simply dial *#*#308#*#*.
