Sena Cases have some new cool cases for your cellphone, that is, if you own a Blackberry 8700c, Samsung i730 or a Treo 700w.

The top image is a not only a leather case for the Blackberry 8700c, but also a mini-wallet. It has space for 2 credit cards or business cards, and an extra space for a random thing such as money.

Accessibility is one of the top features in this case, with easy access to all buttons including the reset one, a headphone and a speaker phone opening. It is also able to work with the sleep function of Blackberry's. And to finish it off, a magnetic type of closure, so you forget the times when a flip case opens itself.

If you want to hang it around your belt, the Bandam Belt Clip is an optional product. The Sena case for the Blackberry 8700c costs $50, and is available in 3 colors - black, red and tan. More images here.

The other cellphone that deserves a case from Sena, is the Samsung SCH-i730. The details are similar to the Blackberry case, just a few changes: addition of a "Hot-sync thru travel cable", and removal of the two extra pockets for credit cards.

There are two models for the Samsung case, one for the extended battery, and one for the standard battery, be sure to check this out if you're interesting in buying one. It costs $46.99 without the Belt Clip, and $49.99 with it.

Finally, the other case is for the Treo 700W and come in various styles: leather, magnet flipper and lateral pouch.

I have some doubts about the success of the Lateral Pouch case (see it here) because you'll have to open the case to use the Treo, unlike the other cases. The Flip Case with magnetic closure looks pretty good (see it here) and gives good protection, while the leather case also looks good but the protection seems to lack - More information about all the models.
