Address+ is a great drop-in replacement for the default address book application. It features 4 commonly used sorting methods, including First Name sorting, easy record duplication, an optional letterbar, a robust group manipulation feature to ease your record maintenance, the optional ability to timestamp a record each time you edit it, 100% compatibility with your existing address database, and now with Font and Beaming support!
The interface of Address+ is very similar to the built in application, so you'll be up to speed with Address+ in no time. 4 on-screen buttons allow quick selection of the sorting method. The (optional) Letter Bar allows you to quickly jump to your desired record, highlighting the first record that begins with the letter tapped. The Group Edit screen allows you to do Deletes, Category changes, Toggling of Private status, and easily changing the default phone # shown for multiple records all at once. Fonts are supported for both OS 2.x and 3.x. Beaming support is finally here!
