Yahoo’s email users will no longer have to worry about a storage limit on their accounts. John Kremer, vice president for Yahoo Mail, announced the change to unlimited storage, which will begin in May. “When Yahoo! Mail launched 10 years ago, users got a whopping 4MB of storage for their entire mailbox. Today, you would fill that up with a single picture from your weekend, ” Kremer said. Kremer also went on to say “as much as we’d like to just flip a switch and ‘unlimit’ everyone on the same day, we’ll be rolling this out over a few months to facilitate a smooth transition.” Yahoo’s email service has transitioned over the years just like technology has in storage capacity just 3 years ago in 2004 Yahoo offered 100MB as the limit followed by 1GB in 2005.

Yahoo also announced a strategic partnership with Virgin Mobile today. The agreement will launch Yahoo! Mail and Yahoo! Messenger in early April available through Virgin Mobile’s Email & IM offerings. These applications will be available for download on several of Virgin Mobile’s handsets including the Switch_Back and Cyclops and will be preloaded on selected future phones. Yahoo! Mobile Web will also be prominently featured in Virgin Mobile USA’s Surf the Web service beginning in April.

Business week reports plans by many social networking sites to bring in third party developers to attract more users. Some sites opening up their networks include Facebook, Myspace, Linked-In, Friendster and Google’s Orkut. Virgin Mobile became one of the companies interested in these mega-networks.

Vice President of Value Added Services Dom Tolli wants Virgin’s four-point-six million customers to browse their preferred social-networking site. Virgin has access to an application program interface to satisfy the needs of many members. The API programs help developers create new functions to communicate with existing programs. E-Bay’s senior manager Adam Trachtenberg understands why businesses need to obtain third-party developers.

“Social networks have reached a point of maturity, and opening API’s will help them grow.”

eBay made software available for others to connect to its site, and web site owners post around 40 percent of its listings. Marketing Director Jeff Roberto opened Friendster up to its software around six months ago showing the visitors increased to 17-point-six percent or up to 18.8 million people.

“This is our biggest month-over-month growth since launch.”

Facebook, orkut, and Friendster verify making their software available to developers. Myspace declined to comment.
