If you’re on the hunt for an iPhone 7, iStockNow makes that task easier by showing exactly which stores have some in stock. The site mashes up Google Maps and Apple’s own back-end inventory system to drop pins on ever Apple Store. Green pins mean a store has some iPhone 7 inventory, and red means they’re out of stock. You can also set filters to see if the size, color, and carrier you want are available, and you check specific cities, too. We were able to tell right away that Colorado and California are good states for getting a new iPhone right now; Washington and Florida, not so much.
