Knowing that there was a going to be a queue for the iPhone 4 anyway, I bought mine online by - get this - installing a special "Apple Store" applet on my iPhone 3G and buying it that way. This actually ended up being the best possible buying experience: The phone came about a week earlier than they said it would. Because I'd bought the new phone by running an app on the old phone, it made the upgrade process 100 percent painless; the old phone's data was automatically part of the purchase, the new phone literally got activated on my existing phone number the moment that I plugged it into iTunes, and the old phone got deactivated.

I've since jailbroken/unlocked the old phone just to mess with it. (I like to keep my daily driver phones "legal" and under warranty, but getting the new phone allowed me freedom to do whatever I wanted with the old phone.) I verified that a T-Mobile SIM works in the thing. Anyone want a 3G?
