In the past I’ve switched cell phone providers from Sprint to Verizon, then with Verizon from one phone (LGV3100) to another (LGV4400B), then to AT&T and have noticed a disturbing lack of functionality. I can’t believe that with all the games, ring tones and screen savers on phones nowadays there isn’t an easy way to upload or export your phone numbers and names to another phone (without buying some extra device). It took me about 30 minutes to key all the names in, multiplied by the number of phones. I don’t see why I should ever have to type them in twice.
Why not have an infrared port to send them all, or a cable that could be connected between the two phones. Or maybe even an upload feature that would allow you to store it to a web site, then download it to the other phone. Maybe this exists and I’m not aware of it, but you’d think they would want to make it easy to switch phones and thus make it very clear how to do it.
