What cell phone provider and device do you have?

After three frustrating days, I finally have a cell phone again. I had previously been a client of AT&T, but I found their data plans to be outrageously expensive. And, to make matters worse, their phones were far beyond any price point that I could afford. So, about a month ago, I switched to Sprint. I had a Blackberry to start, but quickly upgraded to the LG Optimus S (Android, 3G). However, after the switch, I found that I was dropping numerous calls per day and then had issues with voice quality. And, when it came down to the customer service agent I spoke with, I decided to cancel my service. I was told I was within my 30 days and would not have to pay an early termination fee, but that turned out to be wrong. And, after a call from their service center came in telling me that it was my device and not the service that was an issue, I decided to reinstate my plan. Well, that would've been all well and good, but it took MANY phone calls to get things situated. Finally, I'm set and my new phone arrived today, but I am still leery and am waiting for the next shoe to drop, so to speak. Even after talking to numerous customer service agents and checking my account online (everything appears to be correct), I am having trouble trusting that some crazy issue won't arise and throw me off. But, I'm trying to have faith and just let go of my anxiety over the situation. However, this post isn't really about all of that, I'm more interested in what cell phone provider and devices you have. And, of course, whether you're happy with the service and the phone.

As for me, I just received my Samsung Nexus S 4G from Sprint. It's a Google phone and, so far, I really like the design. The voice quality is excellent and I have the same access to all of the apps and programs that I had with the LG Optimus (which I didn't like). The screen colors are vivid and the screen responds to a light touch, which I like. It's intuitive to use, but it'll take me a while to figure everything out and get comfortable with all of the available features. And, I have to stop at the Sprint store this evening after work so that I can buy a gel cover and screen protector. This phone is way too expensive for me not to protect (I do have insurance on it). I'm hoping my issues with devices and Sprint is in the past because their customer service team, as a whole, has been wonderful. And, I don't want to have to figure out another phone to buy. I was lucky to get this one free as an upgrade. I don't think I'd make it through this process again and this phone is mine for a year, at the minimum. I'm just thankful to be back "up and running."

So, what provider do you have? What phone do you have? And, do you like it? Inquiring minds would like to know . Okay, it's just my mind that wants to know, but still...
