I was thinking about getting this phone when I started looking for a new one about 6 months ago, I just got to where I wanted to look for another one again. I currently have a rooted ZTE Warp. It's Satan. I was wanting to get the LG Optimus F7, but I can't afford it, and I'm in need of a phone that can actually work. I was wanting to know if you guys have any problems with yours and how long you've had it. How does it compare to the GS2? Which colors work with the app Blink? If I did get this phone, and a month or two down the road, would boost let me trade it in for a different phone, and just let me pay the difference? Thanks!
