I've definitely had it for more than 30 days and it still works. 8100 on T-Mobile. There was another thread with the links posted. That, or just go to the Mapquest site and enter in your phone number and they SMS you the link.
There is a [link;URL="http://www.blackberryforums.com/gps-mapping/85254-mapquest-navigator-free-trial.html"]http://www.blackberryforums.com/gps-mapping/85254-mapquest-navigator-free-trial.html[/URL]
over in the GPS and Mapping section, but will answer the questions here.
Use the Mapquest.Com website and select Mobile. Click the "30 day free trial" link and select the Sprint 7130e model phone. It will ask for your phone number in order to send an SMS to.
Be sure you have good signal strength before downloading, otherwise, you may have multiple download failures.
Supposed to be free for 30 days, after that $10 USD. It should prompt you to contact Customer Service to register, but a poster above said it was still going. I have an email from them that says it is good for 90 days before having to activate.
For Pearl (8100) users, I just tried this morning on the latest OS 4.2.1.101 and all audio was coming through my BT headset. Downside was that all the words didn't come through because it had to open an audio connection to the headset, say the phrase and then disconnect. During the open, it didn't pause to say the phrase so you would here, ...(in 400 fe)et, turn left.
