That's not true unfortunately. When use the Beta version of store inventory it will show availability if they have phones physically in the store but those phones are ONLY for pre-orders. If they actually have any in store for store purchase, when you click on the phone you want, and put in the zipcode, it will show In Store Only in red letters instead of Unavailable. If you call the stores that show availability under the Beta version of store inventory, they will tell you the phones they have are for preorders only so it's misleading and confusing.
Fascinating.. I guess I'll stop checking and just wait for the email from Holmdel.
