Always charging - bad for battery?

Question

Always charging - bad for battery?

So I work and read at my Macbook Pro many hours a day and leave it plugged in most all the time. Since getting my iPhone 3GS I have gotten into the habit of leaving it plugged in via USB to my laptop most all the time I'm home and only unplug it when I leave home - is this bad for the iPhone battery?

Macbook Pro 2.2 GHz, 2 GB SDRAM, Mac OS X (10.6.2)

No, it's not a problem. Li-based batteries like the one in the iPhone don't have a 'memory' and the battery will stop charging when it's full.

Apple does recommend putting it through a full charge/discharge every month (battery calibration).

NO, don't worry with that, sometimes i charge my iphone just a bit, or too much and never had problems, ( i have it for almost a year) , this kind of battery just need to be calibrated like once a month, or once each 2 months and thats it.
