Other than the password delay. Should be roughly the same. The Palm (and I believe BB) versions remember the last category you were in and have a search feature. If you define your phone number to be a viewable field (once you unlock it), then it should be a 'see and click', 'scroll and click', or 'search and click'. I wouldn't imagine anyone defining the phone number to be a hidden field.
So, to answer your question more directly; I would imagine it to be the same or possibly better as you will probably have fewer of them within SplashID.
