Earlier today, Apple released another update to the iPhone SDK for the iPad, bringing the current version of that SDK to 3.2, beta 4. The update follows one released several weeks ago.
We have not yet heard about any new features in beta 4, but these details will likely surface soon. (In the meantime, take a look at what.)
This OS release appears to be updating approximately every two weeks, a pattern similar to that of the iPhone OS 3.0 launch in 2009. If the pattern continues, you can expect a firmware update for your new iPad to be available on, Saturday, April 3, 2010.
