Well well well. What do we have here? A Sprint copycat promotion? It would appear to be just that. It's looks like Sprint isn't liking that T-Mobile is taking it's customers so it wants to return the favor and offer new and former customers the opportunity to come back--and they are willing to pay you up to $650 to do so. Much like Magenta's "Uncarrier 4.0" program, they will give you up to $300 for your smartphone trade-in from ANY other national US carrier (AT&T, Verizon Wireless, or T-Mobile), plus up to $350 in the form of a prepaid Mastercard to cover your early termination fee (ETF). Don't have an ETF? No problem! They'll give you up to $350 towards your EIP (financed device balance). Starting today and only through May 8th, Sprint wants you back in the worst way, and are willing to duplicate a now famous T-Mobile promotion to do it. Of course, you'll have to purchase a new Sprint phone and sign a two-year agreement, port in your number, and probably have to put up with crappy service in the process. But you're getting away from your old carrier scott-free right? Whoever said that imitation is the sincerest form of flattery wasn't kidding. Better read the fine print to get all the details Kids!
