I've been a loyal Sprint customer for over 12 years...er...let me rephrase that. I've been a Sprint customer for over 12 years, and during this time i've experienced the good, bad, and ugly of their services. I remember all of my friends envying my Samsung A900 (and A900M after) flip phone. Not only did it have a groundbreaking high resolution display paired with a Qualcomm radio chipset capable of harnessing Sprint's new blazing fast 'EVDO rev.A' data protocol, it was the first flip phone to have an App Market, Sprint TV, and include a revolutionary new streaming music service called 'Pandora;' all packed into one of the thinnest flip phone packages ever seen (until the Motorola RAZR's debut).
Then everything changed when Cingular was swallowed up by AT&T. With AT&T's monopolistic capital to throw at Cingular's infrastructure, the GSM spectrum exploded across the country, and by marketing the versatility of "SIM Cards," Sprint and Verizon promptly shat bricks.
I could continue to rant, but i'll spare you.
To summarize, I've been on the phone with Sprint's retention department over the years and every time they've made a conscious and notable effort to keep me as a customer. In the years when I also had a second line with T-Mobile and AT&T, and subsequently cancelled my plans with them, their retentions departments could've give a rats åss if a customer was lost.
This tri-band torture is killing me as a resident of SF using a Nexus 5; frustrating to the point of finding myself considering reactivating my Galaxy Nexus and getting an AIO plan for my N5 until the towers are upgraded, but since Sprint has pulled weight to keep me as a customer, I will reciprocate by giving them 6 months to fix San Francisco before I throw in the towel.
