Good news for those in the USA that have been waiting on the iPad 3G. All of the early pre-orders that were placed for the iPad 3G should be arriving April 30, 2010. If you are going to purchase at an Apple store, they will begin selling them at 5PM Local time.
If you pick up a 3G, you will definitely want to try out the contract free AT&T 3G service with them. You can get 250MB of 3G for $15/mo. or $30 for unlimited service. AT&T says this really IS Unlimited, not like their 'unlimited' 5GB services on their air cards.
