This year is shaping up to be a busy one for Apple. So far, the company previewed the fourth generation of its iPhone operating system, announced its new iAd mobile advertising platform, unveiled the iPad and sued HTC.

It also has been a profitable quarter for Apple if analysts’ estimates come true.

Apple is expected to beat its earnings forecast for the second quarter when it reports results after market close today. Company CFO Peter Oppenheimer said last quarter that Apple expects diluted earnings per share between $2.06 and $2.18 on sales of $11.0 billion to $11.4 billion.

Analysts polled by Bloomberg and Yahoo! Finance expect Apple to beat its forecast. Bloomberg analysts expect Apple to post earnings per share of $2.43. Those polled by Yahoo! Finance expect Apple to post earnings per share of $2.45 on sales of $12.04 billion.

Since Apple’s first quarter ended March 27, the iPad won’t affect today’s results. Apple says it has sold more than 500,000 iPads since the device launched on April 3 and recently announced it had more than 85 million iPhone and iPod touch users in 90 countries.
