has just released an updated version of the popular MP3450i: the 3rd
revision, MP3450i R3. The previous R2 version added a USB port for
charging/powering USB devices such as iPads, phones, MP3 players, and
much more. Now, instead of a lithium polymer battery, the R3 uses a more
stable lithium ion battery. 3Gstore is ONLY stocking this latest and
greatest version of the battery pack (and at the same price as the R2:
$189.95), so beware of other companies selling the MP3450i because you
may be getting the older R2 or even the original version!
