What was the last dumb phone you had before your first smartphone?
I rocked a Samsung Alias 2 for 4 years before I got an iPhone 5. The e-ink keyboard was awesome how it changed when you flipped the screen open to portrait or landscape.
LG enV Touch. The thing was actually awesome. Music player was dope, touchscreen worked well, full physical keyboard, and the browser could load Flash. The web browser wasn't perfect but was on par with the blackberry of the time.
