The phenomenal growth rate of Google's Android continues to increase, according to Android chief Andy Rubin.

The Google vice president announced in on Google+ and Twitter this evening that "There are now over 700,000 Android devices activated every day," clarifying later on Google+ that "for those wondering, we count each device only once (ie, we don't count re-sold devices), and 'activations' means you go into a store, buy a device, put it on the network by subscribing to a wireless service."

The new growth figure shows significant escalation in that it comes a month after Google announced that 550,000 devices were being activated every day--up from a daily tally of 500,000 in June and 400,000 in May. The company also announced last month that more than 200 million Android devices had been activated around the world.
