I am always of the opinion that all numbers on a GSM phone should be stored with the + sign. Makes life easier when one is travelling internationally. I did exactly that on both of my GSM phone. The manuals that came with the phones even suggested that.

It's also true that the CDMA phones do not understand or even allow the + sign to be included as part of a phone number. My CDMA phone is fairly recent and does not have the + sign on the keypad.
