Banking goes mobile (via Time magazine).

"The electronic wallet got one step closer to reality on Monday when Citibank unveiled a cell-phone-based service that lets customers pay bills, check their account balances and transfer funds, regardless of which wireless carrier they use. The free program, Citi Mobile, will be available for customers in Southern California via download this week at Citibank.com and will go nationwide this summer. AT&T, Sprint and Verizon customers can start using the program this week, with other carriers and a Spanish-language version out later this year. "
