Four of the seven Galaxy S smartphone models.

Samsung's Galaxy S smartphones have reached another milestone.

The company said today it has now shipped 3 million Galaxy S smartphones. The figure comprises sales of the seven models of Galaxy S smartphones, including the Fascinate, Captivate, and Vibrant, currently available from all the major carriers. The announcement comes about three months after Samsung said it had shipped 1 million of the phones, which run on the Android operating system.

Samsung also noted today that it plans to upgrade the phones to Android 2.2 "in the near future." It wouldn't provide an exact time frame for the update.

On a related note, reports have been swirling that Samsung has sold 1 million units of its Galaxy Tab tablet. After initially telling CNET today that Samsung had not officially announced sales or shipments of its tablet, a company spokesperson then contacted CNET again and confirmed that sales figure.

Samsung's Galaxy Tab features a 7-inch display and runs Android 2.2. The device has been on store shelves for about three weeks.
