News broke yesterday that former Apple Senior Vice President Tony Fadell’s Nest Learning Thermostat will soon go on sale at Apple Stores. iLounge reported it first, but 9to5Mac immediately confirmed the claim.

A trusted source provided a first-hand look at the Nest packaged at an Apple Store today—complete with the part number. Priced at $249.99 (the same as Nest’s price through its online store), the Nest has a part number of H9279ll/a in Apple’s systems.

Our source was not able to say when the Nest will go on sale at Apple Stores, but the source indicated it will be soon. Deliveries of the Nest are now being made at multiple Apple Stores. However, we are hearing whispers that the thermostat may not go on sale at all stores simultaneously.

For those unfamiliar, the Nest is a revolutionary new digital thermostat with an intuitive temperature dial. It is controllable by iOS devices such as the iPad, iPhone, and iPod touch. A photo of the back of the box (complete with Apple’s price tag) is after the break.
