a plurality of faceplates,

each faceplate of the plurality of faceplates configured for removable attachment to the front face of the standard housing,

each faceplate of the plurality of faceplates removable to permit replacement of the each faceplate by another faceplate of the plurality of faceplates for customizing appearance of the portable radiotelephone handset,

each faceplate of the plurality of faceplates having a substantially identical faceplate attachment structure configured to engage the housing attachment structure to securely retain the each faceplate of the plurality of faceplates to the front face of the standard housing,

at least one faceplate of the plurality of faceplates having a keypad cover movable between a first position and a second position, the keypad cover covering a portion of the keypad in the first position and exposing the portion of the keypad in the second position.

2. A portable radiotelephone handset as recited in claim 1 wherein the at least one faceplate of the plurality of faceplates further comprises a body and a hinge coupling the keypad cover and the body, the hinge providing rotational movement of the keypad cover between the first position and the second position.

3. A portable radiotelephone handset as recited in claim 1 wherein the front face includes a recessed portion defined by a perimeter and a nonrecessed portion, and wherein each faceplate of the plurality of faceplates has an outer perimeter configured to conform to the perimeter of the recessed portion to provide a substantially flush fit between the faceplate and the non-recessed portion.

8. A portable radiotelephone handset as recited in claim 1 wherein the faceplate attachment structure comprises a plurality of tabs arranged at a perimeter of the each faceplate of the plurality of faceplates and the housing attachment structure comprises a like plurality of slots positioned to receive the plurality of tabs.

4. A portable radio comprising:

a housing having a front housing portion and a rear housing portion, the front housing portion including a housing attachment structure;

a keypad including a plurality of keys configured for attachment to the front housing portion;

a faceplate removably attached to the front housing portion to permit replacement of the faceplate by another faceplate, the faceplate including a faceplate attachment structure and the other faceplate including a substantially identical faceplate attachment structure, each faceplate attachment structure being configured to releasably engage the housing attachment structure, the faceplate including;

a first end and a second end;

an outer surface defining a plurality of keyholes, each keyhole sized to receive a key when the faceplate and the keypad are attached to the front housing portion;
