I went into a local store a few days ago to see the new Centro since I was looking for an entry level Smart phone. The salesman couldn't give me five minutes with no one in the store. He said his 'boss' would have the phone in a couple of days and they'd call me back. Never heard from them again. I went looking for online reviews and wasn't impressed - moved on. Haven't heard or read anything good about their service anywhere recently either.
I've been with them for years, before the takeover of Nextel, and one thing I know for fact is that Sprint does not care at all. The phones are terrible. The Palm Centro? The LG Rumor? What is this, a joke? And don't say the HTC Mogul because not everybody likes to pay $300 dollars for a smartphone (see: Blackjack 2) And the customer service is God-awful. Only if wireless carriers actually cared about what their customers think of them. Big if.
