I had CM on it and that was the ONLY silver lining. I had the phone for the entire 2 years of my contract. It was so slow, I would have about 3 seconds to answer a call before it went to voicemail. I guess it could have been network issues, but I think it was the phone. Then there was the issue with memory. I think it had a 3.5" floppy disc for its memory. I could keep approximately 7 apps installed before overflowing the memory. I had to continuously uninstall and reinstall Yahoo's fantasy football app to clear out the data (there were several times where it reached 25 MB and it was unable to just clear out the data.) The only thing I can say for it was that it was really durable. There were several times that it met concrete at a high rate of speed and after re-inserting the battery and putting the back cover back on, it fired right back up. Then you add the fact that everyone else was using the Evo, and I was very unhappy with the HTC Zero.
