If you've been considering jumping ship from your current carrier and hopping over to Sprint, you may want to finalize that decision before June 23, 2011. Why is that, you ask? Because until that date, Sprint will give you $125 per line if you port your existing number over (with a qualifying smartphone or data plan, of course). That's right, you will get paid to switch carriers.
Here's how the deal works: buy a new smartphone from Sprint's online store, transfer your number over (you should be prompted to do so during checkout), and register for your credit within 72 hours of activating your phone.
