Well, I have to hand it to the voicemail folks. I have an older version and when I downloaded the new version on my 700p my original registration code is not valid.OK I can uderstand that they have some new features. But then I had my original email from Handango and downloaded the version I have on my 650 and when I installed it on my 700p it says not valid for this device. From my email it states

If you have your Treo 650 repaired or replaced(I asssumed this meant with a 650 or equivalent OS phone) and need a new registration key to unlock the Voice Dial application, simply email: treovoicedial@handango.com with the reference number included in this message. At no cost to you, you will then be eligible to reregister the application.

Should this be an upgrade?
