Starting on Friday, Apple's U.S. online store will accept pre-orders for both the WiFi-only and the WiFi+3G models. Apple's retail stores, however, will reserve only the WiFi iPad for pick-up on Saturday, April 3. The iPad will be available in late April in Australia, Canada, France, Germany, Italy, Japan, Spain, Switzerland and the U.K., Apple said last week.

Prices for those markets won't be announced until next month.
