I just got the newest Sanyo MM-8300 and this Holster doesn't fit! The phone will not stay in the holster no matter what I do. If the phone is in a leather case it will fit securely but I know over time it will probably break it, being such a tight fit. It will also ruin the leather case. Luckily the leather case I got has a belt clip on it anyway, it doesn't swivel, but it's better that this Holster.
