Google's reasoning was that even though the app itself is harmless, "it encourages users to void their warranty" and therefore would not be allowed to remain in the store, CyanogenMod explained at the time. It sounded like a bogus excuse, but here we are three weeks later and Google its blessing to a phone with the CyanogenMod ROM pre-installed.
"Man, the last 24 hours has been a total roller coaster of emotions, and it isn't letting up it seems," CyanogenMod developer Koushik Dutta posted on his Google+ page. "Google just approved our build for production... we're shipping the CyanogenMod version of the N1 on Christmas Eve."
Dutta didn't add any other details, but what this means is that the Oppo N1 is the first phone outside of Google's Open Hardware Alliance (OHA) to pass the company's Compatibility Test Suite (CTS), meaning it's allowed to run the Google Apps suite legitimately, as opposed to users side-loading it themselves.
