It was quite frustrating today trying to upgrade to the iPhone 4 because, due to an error in the ATT servers, it was pretty much impossible to order, until all the launch day units were sold out. I will be so glad when Apple’s exclusive deal with ATT is over.
Update: It turned out the orders did go through. Days later I got confirmations that the ATT orders I placed would ship for launch day, and that one of two units I tried to order through Apple would be at the store in Skokie.
