Burger King wants its customers to use its new branded mobile app for Android. It wants this so bad, the fast-food company is giving away Android smartphones. This promotion is quite a bit more advanced than the usual “Jungle Book” toys or “Star Wars” glasses giveaways. You can’t just roll up into the drive-through lane at your local BK and get a deep-fried Galaxy S3 dropped into your bag next to your Whopper. The offer is available online and it does have some strings attached. The free phone requires a new or upgraded two-year agreement with AT&T, Sprint, or Verizon. This comes with all the usual rigmarole of signing up with a cell service provider, including possible credit checks, activation fees, early termination fees, and deposits.
