Why should I stay with Sprint?

[ganjah]

So, I have a real problem. I've been with Sprint for 10 years as of this August. I have perfect payment history and a credit rating above 780. I currently own the HTC Hero, which has been a good little phone, but I want to upgrade. I have the $150 credit to get a new phone, but that's where the issues begin to crop up.

My current contract expires Feb. 19, 2012. Because of successful negotiations in the past with Sprint's Executive Services, I pay $36 and change after taxes and fees for the following:

I don't use a whole lot of minutes (mostly mobile-to-mobile), don't use a whole lot of data (never more than 2GB/mo), and my max texts are typically around 3500/mo.

I want to upgrade my phone, and I'm considering the SGS2. I have been in contact with Executive Services recently, and the lowdown is that if I want to get a new phone, I will have to pay $200 for the phone. Then, since I was grandfathered in, I'll have to pay the premium data fee of $10/mo. But, I will also have to renew my contract and I will lose the extra $20/mo service credit that is currently offsetting the price of my service. I will retain my corporate discount of 27%, but, all told, after taxes and fees, simply upgrading my phone for $200 will actually increase the price of my service to about $65-70/mo after taxes and fees. This is nearly doubling the price of my service, and without a free phone to boot.

This is nearly the price of similar competing Verizon and AT&T service plans (after my corp discounts there), but Sprint doesn't offer 4G in my area (Albuquerque, NM), and their 3G service is spotty, at best.

Why should I stay with Sprint? Are there better options? Anything that offers premium phones for close to the same price I'm paying now?



TL: DR Sprint's jacking up my monthly price by nearly 2x if I upgrade phones, or at the end of my contract in February. Nothing I can do after negotiating with Executive Services. Where else can I go with premium phones for cheap?
