One reader notes that iTunes 4.8 already seems to have localization for Motorola's iTunes compatible phone.
iTunes.app -> Contents -> Resources -> English.lproj -> Localized.rsrc contains the "Eject Phone" phrase as well as later references to "Phone".
Motorola's iTunes compatible phone has been long awaited, with a number of delays reported. Last comments from Motorola claimed that it would be coming in "a couple of months" from May.
It appears iTunes may already provide support for the phone.
