NEW YORK ( TheStreet) -- Popular searches on the Internet Wednesday include Iran on news of the country's plot to assassinate Saudi Arabia's ambassador to the United States.

Iranian agents reportedly attempted to hire a member of a Mexican drug cartel to assassinate the Saudi ambassador on U.S. soil.

Now, the U.S. government plans to try to tell the world not to deal with the Iranians in an effort to isolate the country. The administration will lobby for new international sanctions in addition to asking individual countries to heighten their own penalties against Iran.

U.S. officials maintain the assassination plot is a violation of international law as well as an example that Iran is the leading state sponsor of terrorism in the world.


iOS 5 update also is trending. The iPhone 4S still won't go on sale for a few more days, but those with the iPhone 4 and 3GS versions can already start catching up to it.

Apple ( AAPL) is making free upgrades to its iOS 5 software available to those versions of the smartphone on Wednesday. Both versions of the iPad and newer models of the iPod Touch can also use the new upgrade, which includes features like the ability to sync content wirelessly and send texts, photos or video through iMessage.

Apple's new iCloud service also drops Wednesday.


PlayStation Network is another hot topic. Sony ( SNE) said Wednesday it froze almost 100,000 user accounts on its PlayStation Network and other online services after it detected a spike in unauthorized login attempts.

Sony said it suspected that hackers obtained user login data from other sources online to try to gain access to user accounts, though only a few accounts are believed to have been accessed and no sensitive information obtained.

This follows the data breach against Sony's network in April that compromised 100 million online accounts and forced the company to temporarily shut down PlayStation.


The chatter on Main Street (a.k.a. Google, Yahoo! and other search sites) is always of interest to investors on Wall Street. Thus, each day, TheStreet compiles the stories that are trending on the Web, and highlights the news that could make stocks move.
