There is a rumor that Apple will start talking preoders for the iPad deliveries on 2/25 (this should not be confused with an official release date which can be defined as a date the first iPad units will be shipped or physically sold).
You’ll remember that this is almost 5 weeks sooner than the initial WIFI model March shipping date I blogged about back in January
The preordering process would be limited to customers in the USA (the article also has a blurb on a supply chain pressures that Apple might be facing with such a short release window).
Take this info with a grain of salt as this is just one in a long chain of speculations revolving around the potential iPad release date.
