Hoping to avoid tomorrow’s lines at Apple and AT&T retail locations but still looking to bag yourself a new 3G S? Thanks to a MacRumors forum member, it might me easier than you think. Amacfa has obtained what he or she claims to be Best Buy Mobile’s complete iPhone 3G S inventory for tomorrow’s launch and has posted it as a public spreadsheet on Google Docs. While it is not known how many units are spoken for due to pre-orders, you will definitely be able to get a good idea of which stores in your area have a healthy 3G S inventory and which ones you’d be better off avoiding. Assuming the sheet is real, that is. Hit Best Buy’s site and use the store locator to determine the store numbers for your local Best Buy locations and then hit the read link to see what kind of inventory you’re going to be dealing with. Better act fast though — according to the sheet, Best Buy locations across the country will only have a total of 17,580 iPhone 3G S units on hand for launch day.
