We all know AT&T likes to lock down Android devices for our protection, how nice of them. Â This also means those Android owners are also shut out of things like the new Trillian beta app. Â You can root your Streak, but for those who for whatever reason don’t want to take that step, there is another method available.
- 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.
You’re done! Now go back to Home, and press Menu. Go to Settings > Applications, and you should now have an “Unknown Sources†check box available to you. This will now allow you to download any app of your choosing directly from a webpage or SD card. If for any reason you want or need to uninstall the EMList, simply go to your dialer and type in the following keys:*#*#308#*#*.
Voila, your Dell Streak can now download any app that is compatible with the OS.
