Leaving iPhone on charger overnight - bad for battery life?

Does leaving the iPhone on the charger all night damage the overall health/life of the battery? I was told a while ago by a Mac Genius that I shouldn't keep my MBP plugged in after the light turns green, as it will decrease the overall life of the battery by overcharging it. Is this true as applied to iPhone as well?

iPhone 3GS, iPhone OS 3.1.3

The battery charging will stop when the battery is fully charged. I leave mine on a charger overnight every night. I do follow Apple's advice to run the battery down once a month or so and then recharge completely.

Apple does not recommend leaving your portable plugged in all the time. An ideal use would be a commuter who uses her MacBook Pro on the train, then plugs it in at the office to charge. This keeps the battery juices flowing. If on the other hand, you use a desktop computer at work, and save a notebook for infrequent travel, Apple recommends charging and discharging its battery at least once per month.
