I've noticed that on the 1st - 4th of the recent months  (since January), several sites I maintain are getting thousands of requests from mobile browsers, whereas throughout the rest of the month, the numbers are in the single or double digits.Has anybody else noticed this sort of behavior?I don't have the exact user agents logged, but my analysis software (WebTrends) reports the traffic as mostly iPhone/iPad/iPod, Android, and Blackberry.
