Apple has issued an advisory regarding launch-day availability, warning customers that retail stores may have very limited stock of the iPhone Duo for walk-in purchasers.

Shoppers hoping to secure the new smartphone in person without an existing pre-order or pickup reservation may encounter shortages. The alert points to tight initial allocations or strong early demand, making spontaneous store visits risky for eager buyers.

While specific inventory numbers by location have not been detailed, prospective buyers are generally advised to explore online ordering or scheduled store pickups where possible to guarantee a unit.
