My brother, who is not a techno-geek, showed up for his new job and was handed a 7520 BlackBerry with Nextel service and told to carry it all the time. They trained him how to use the e-mail and phone functions and that's about all. We were looking at it and saw that it had GPS, WAP, Java and long list of other features. I spent some time today reading the manuals from the Sprint/Nextel website. I'm curious about what (if anything) can be done with this device that Nextel won't tell me? For instance, it seem to have a J2ME environment. Does the 7520 support 3rd party J2ME applications? Are there any particularly handy ones? Any place I should look for hints, cheats, etc? Can you tether via Bluetooth?
