The V3r and V3t are models sold by T-Mobile, AT&T (formerly Cingular), and Canadian cellular services such as Rogers Wireless. These models are virtually identical to the V3 and V3i, except they use Motorola's Digital Audio Player instead of iTunes for music playback. T-Mobile's V3r offers a Voice Notes feature which permits forwarding your audio recordings to voicemail as the only storage method. However, a publicly available seem edit permits users to enable the hidden Voice Records feature. Voice Records allows you to save voice recordings locally to phone memory. Currently, Voice Records is limited to less than two minutes of audio recording and stores the resulting records as .avr format files on the a partition within phone memory. In contrast, currently available seem edits can expand the maximum size of video recordings. (*)
