I saw someone here that said it seems to be working, then emailed Sprint and they said............
"Thank you for contacting Sprint together with Nextel. I will be happy to assist you regarding your phone.
I noticed that the Telenav is not available for Blackberry 7130e. I apologize for the inconvenience this may have caused to you."
...and then informed them of this link: TeleNav Download Center
Just a bit hesitant and wanted to find out if anyone else is using and if it is indeed working with v18.104.22.1689
