The New York Times [registration required] reports that spouses are using electronic means to spy on their significant others. Here are three examples:

• Research in Motion Ltd.'s (NASDAQ: RIMM) BlackBerry uncovers a husband's affair with a medical resident. One woman noticed that her husband, a Manhattan surgeon, was distant and obsessed with his BlackBerry. She drew him a bubble bath on his birthday and then pounced on the BlackBerry while he was in the tub. His e-mail messages documented his affair with a medical resident, including plans for a liaison that night. A few weeks later, she found messages in his AOL e-mail from a mortgage company proving he'd purchased a $3 million Manhattan condominium for his trysts with the medical resident.
• Time Warner, Inc. (NYSE: TWX)'s AOL e-mail reveals wife's Australian lover. A Philadelphia man believed his wife was engaging in secret online correspondence. He found e-mail messages to a lover in Australia that she had sent from a private AOL account on the family computer. The man's lawyer used the AOL e-mails as evidence to help win a legal dispute between the man and his wife and an advantageous settlement.
