Reuters' Sinead Carew reports that AT&T is introducing a new service called AT&T Unity that will "let subscribers who pay at least $110 a month make unlimited calls between their mobile and home phones."

Carew says the service will be offered as a "perk" for subscribers who pay for both a $50-a-month unlimited local and long distance wireline plan and a $60 a month unlimited wireless plan. According to AT&T, about half of its 58.7 million wireless customers already use its wireline services, so it's a logical next step to reduce churn.

Calling it "a desperate cry to save wireline," Om Malik writes, "AT&T's Unity plan is a bandaid solution that can't really stop the bleeding. Sure it will help the company retain (or even attract) some customers to its rapidly declining wireline business, where it still makes a lot of money, and extract more out of its increasingly redundant copper lines. How long can this game really continue? That is the big question."
