iPod Touch/iPhone and TPRI – Updated
I did some research and it would appear that Wireless Generations(makers of popular palm os software for TPRI) has no immediate plans to update their product to the iPod touch platform. Since the palm OS is no longer being developed, I think this is a mistake on their part. They are leaving a huge market wide open that another company will hopeful capitalize on soon.
After digging for a while, I was unable to find a company that has a TPRI product available for the iPod touch. I thought that I had a product located previously, but that company decided to not develop the product. It would appear that wireless generations is our only choice, as poor as it may be.
Update:
After receiving a few comments, it appears that Tango Software is now offering a iPod Touch/iPhone and iPad solution for TPRI. We looked into it at Chapel Hill and are very interested in what they offer. I will create a new post and let you know what I find out after we implement it.

We are doing TPRI on the iPod Touch and also the iPad. Let me know how we can help!
We’re using Tango software next year.
