Andy Rubin said that Google had a cunning plan that it could flog the phone over the Web and people would buy it as they already do electronics like digital cameras.
Speaking at the D: Dive Into Mobile technology conference Rubin said that the problem was "one of scale".It would seem that the term "one of scale" means that it was too much like hard work.
For each wireless operator it worked with, it had to do things like set people up with phone numbers, perform credit checks and more, he said.
It was taking far too much time and there were more than 150 carriers worldwide.
In the end Google could not be bothered and it seemed a better idea to focus on things like building newer versions of Android, he said.
The Nexus S, the follow-up to the Nexus One that Google and Samsung Electronics unveiled Monday has been released on the premise that it is an unlocked phone.
However, it will be flogged in the U.S through Best Buy Co. stores, which already have systems in place to set customers up with wireless carriers. The phone will cost $529 unlocked, or $199 when bought with a two-year T-Mobile contract.
