Mobile phones have come a long way to the point where they are now capable of performing similar tasks to the PC. Increased hard drive capacities, coupled with WiFi accessible phones and 3G technology, makes the mobile phone ready for heavy duty Peer 2 Peer file sharing. Mbit, which is currently only available on Nokia and Sony Ericsson phones, allows users to swap photos, music and videos over their network. Like a regular P2P network, Mbit transfers files from one user to another in chunks, meaning that mobile users can begin a download and then seamlessly pick it up again each time they lose their wireless internet connection. With over 200,000 users already signed up around the world, MBit has taken a significant step towards fulfilling the most difficult of P2P tasks, which is of course, making sure there are enough peers sharing to make the service useful.
