Since going on sale, analysts have expected a healthy shipment of iPhone 3GS’ but it seems supply problems may soon plague Apple.

A short while after the iPhone 3GS went on sale, Apple brought back its availability tracker which showed how many units a store had in each color and capacity. According to Macrumors, iPhone 3GS availability is dwindling even further than expected with Apple stores in Alabama, Oregon and Utah being completely sold out of all models. It is unknown when new shipments will arrive but if you’re thinking of purchasing an iPhone 3GS, you better hurry!
