I'm going to sound like a negative nancy, but after some casual research I did 6 months ago, I couldn't find any that were reliable as a daily driver cell phone. For profit companies and strict legal requirements for emergency calls and such have a very good track record so far compared to most reviews I've seen. Maybe I just don't text much, but SMS and phone calls are generally very important to me in terms of reliability. I've read some reports about one of the main contenders locking up to prevent even 911 calls in certain cases. I'm sure many of these issues have been addressed, but it's to early for my risk level to use it as a primary device (unless I kept a backup flip phone on me all the time too) Would absolutely love to be proven wrong though. I want to live in a world where the best software is free and open source, and you can flash it to any device capable of running it.
