Iran lifts Gmail ban: Iranian authorities have restored access to Gmail after a weeklong ban on the service, the Associated Press reported.

The service was blocked in response to video clips on Google’s YouTube site that showed parts of an offensive movie that sparked protests. The ban, the report said, has been lifted because authorities are now able to technically separate Google and YouTube.

IAB releases new figures on ad-support economy: The Interactive Advertising Bureau released new figures Monday showing that advertising supported Internet companies contributed $530 billion to the economy in 2011 and are, in some way, responsible for 5.2 million U.S. jobs.

The IAB-commissioned report from Harvard Business School, which updated a similar 2009 report, found Internet-based companies in every congressional district in the United States. About 2 million people are directly employed by Internet ad-supported firms, the report said.

An additional 3.1 million jobs, including those in Internet advertising and digital advertising analysis, would not exist without the sector.

Many of those companies are one-person businesses, including developers selling apps or entrepreneurs selling goods through services such as Amazon, eBay or the e-commerce Web site Etsy.

LightSquared: LightSquared is seeking approval for a new plan that the company says will solve the technical issues that have plagued plans for the national 4G network in the past. In filings with the FCC, the company asked to share frequencies used by government agencies.

In its proposal for modification, the company said that it would not use the spectrum it owns that interferes most with global-positioning satellite systems, and would instead like to use airwaves owned by the U.S. government that are adjacent to others LightSquared already owns.

Apple, Verizon fix data bug: Apple pushed out an update Sunday that should fix a bug in the iPhone 5 that caused the phone to use cellular data even when users were on WiFi networks.

Those who bought the new smartphone noticed that they were being charged for using cellular data even when they were using their phones on WiFi networks. That quickly ate through their monthly data quotas and, in some cases reported on Apple’s support forums, nearly cost some users hefty overage fees.

On Sunday, the company posted a page on its help center telling users how to fix the problem. Verizon Wireless said in a statement to 9 to 5 Mac that it will not charge users for “unwarranted cellular data usage.”
