I ordered two Treo 650s, the second in order to put it on my AmEx.* I'd like to return the second one and get credited on my first card. Is that possible? I know that I could just use the second one and put the newly-activated SIM in from the first.

The reason why I ask is because I've already installed apps, and of course, they all work perfectly (no noticeable crashes or resets, etc.) on this first unit.

Or, are each of the orders tied to a serial or IMEI number? If so, I should simply use the second one and go back to reinstalling apps?

Just trying to figure out the best course of action.

thanks!
