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. Easy peasy.
Naturally, this deal requires a two-year agreement and you must keep the new line active for a minimum of 61 days to receive the credit. We've read through the fine print and this deal looks as legit as they come, so take advantage of it while you can!
Update: Unfortunately, this deal is only available through the Sprint Online store or your local retailer, so you won't be able to get it if you buy your phone through Wirefly, Amazon Wireless, or the like.
