The Best Phone You've Ever Had?

I feel like this is one thing that the future has let me down on. But i understand also that having something that can tell you the personal information f everyone you look at is ultimately a very problematic thing. I wish we could work that out in some way, that it's like if you're the type of person that's fine having a public facebook profile then it can find who you are and whatever information you don't want. Regardless, what is the best phone you've ever had? The best phone? Ye, what's your favorite?
