I have an old unlocked 6710 Blackberry with 8meg RAM and a BES server 4.0. The Berry works as a cell phone, and I even get gprs in lowercase on the display, but it does not send and receive emails. Apparently it needs to belong to some service provider company (e.g. Cell phone company) and the PIN needs to be in their system for it to work. (OS version 3.6) Any ideas? And - can I upgrade to handheld version 4.0?

Tech/Business: Say I were to conduct a feasibility study for social networking via mobile phones. I would like the service to enable people to define their relationships and be alerted when a specified contact is nearby (e.g., within 30m/100ft) - provided that contact has set themselves to be "findable" to that person. Is this already being done? If so, where can I find more information? If not, is this viable? Do we have the technology? How do I turn it into a profitable venture? [more inside]
