How can i check availability of the new iphone at the store.

We have no way of predicting product delivery dates to the Apple Stores. But you can try calling the store. Or open Apple.com and “shop” for the new iPhone Pro. Enter the details of what you want. Before you get to the page where you enter your credit card, you will be prompted to enter your zip code. Then you will see if any stores near you have that device available for pickup. You may want to complete the purchase, specifying “pick up at store” because these are selling out quickly. One last thing - I’m not sure if the store will accept the drop off of your older iPhone. Call. If they don’t, you will receive a return box in the mail. It’s easy to use.
