So far the phone seems very nice; it has a very bright, hi-res, and hi-color display. The phone is fairly configurable, if not initially obvious. For example, I found that the phonebook can be configured to what I expected (that is, have multiple entries per name); you just need to configure it to show the primary contact only; you can then scroll left and right to find the other entries.

I've had problems getting GPRS to work since I have AT&T mMode and this is a Cingular phone (thus, it's had the Cinglar settings pushed to it). I finally did find a page with the mMode settings and how to setup mMode on a v551. This also had to be done in the Email Inbox settings so I can send and receive mail. At least it supports IMAP4.
