I just can't see the average Wallyworld employee sorting out the details of activating phones, doing a credit check in store, etc. Unless they plan on bringing in at&t employees for a "store within a store" concept...
The average Wallyworld employee doesn't do these things. Only associates in the 'Connection Center' (usually part of the electronics 'megaplex') deal with cell phones. The iPhone just adds more to the process. We sign-up new accounts and deal with upgrades and activations at Walmart, but no other phone will require such a process. We have to tether the iPhone to our Kiosks and login to a POS.com system to 'unbrick' (as the manual states) the iPhone and activate it. We're to demo it's abilities and give the customer the chance. As before, they will not be covered by wireless insurance but by Apple's warranty.
No minute or data plans will change and there will be no other exclusivity as far as I can read. No 4GB iPhone. Just the ones we've been seeing, unless Apple has an ace up their sleeve, but I doubt it will coincide with the Walmart launch.
