My Motorola Photon wasn't connecting to 4g for the last week in Manhattan or Queens. I finally got around to calling customer care, and it turns out they've been having an outage since the 14th. I asked for a credit since I have two 4g phones that have been without the 4g premium service that I have to pay extra for, and I was told they would pro rate a credit for the duration of the event once they fix it.
Wimax is not reliable, and if Sprint wants to survive that 4G story that Hesse will tell on October better be good. I have Sprint here in NYC, I never have problems since, but the service indoors is crap. I go outside and bang I get over 9.0 megabits down and 1.50 up. The speed is there, but Sprint using Wimax 2.5 Spectrum band won't help them to compete with the big boys.
