RIM, the maker of the Blackberry, is working on a version that will enable Wi-Fi and cellular access: The company won't say when the devices will be available but said it won't be before the spring.
I was just talking to a friend yesterday who just bought a Blackberry that runs on T-Mobile's network. He was complaining about how slow the connection speed is. I bet he'd love the chance to use Wi-Fi when it's available.
