A simple Dell Streak hack has emerged that will allow AT&T users to sideload apps not obtained from Android Market onto their tablet/smartphone device. AT&T has cited security reasons as to why the carrier isn’t allowing non-Android Market apps onto the device in the past. This hack, which doesn’t require your Android device to be rooted, works by entering a string of numbers into your Streak’s dial pad.
Users will need to:
1. Dial *#*#307#*#* on your Streak. Other than a quick flash on the screen, it will look like nothing has happened.
2. 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.
3. Tap update unknown resource property to enable it.
4. 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#*#*.
