How can I get a free iPhone 5 within 3 days?
Is there any website or app that I could use to participate in contests and win free iPhones?
Yes, there are some websites and apps such as SweepstakesFanatics, ContestGirl, and Giveaway Promote that may have iPhone giveaways that you can participate in. However, you must carefully read the fine print and make sure the website is legitimate before you enter any contests.
