Title says it all.  Andy Rubin just tweeted some more Android numbers and they are pretty impressive.  In the two day Christmas period, 3.7 million Android phones were activated.  Compare that to 1.4 million on an average two day period.

Another comparison: After 16 months without releasing a phone, Apple sold 4 million iPhone 4S’s in the first week of release.

The Android Freight Train continues to roar.
