The Hold-a-PDA is designed for the Treo 600 series; the Blackberry 7100 series, and will also hold the Sony Ericsson K600i.

We wanted to make 1 holder to fit most cell phone PDA's. 
A small antenna opening has been cut for the Treo. 

This holder will hold devices up to 4.75" x 2.4" x .9" although with some stretching they may accommodate a slightly larger PDA.

It will not hold the Blackberry 7520

This holder will also accommodate the iPod Nano and larger 30-60GB
