SlashGear - Never fear, Blackberry Tag isn’t another fail-laced tablet or other device coming from RIM. Tag is a new tech that users of Blackberry smartphones will be able to use to trade and share data with other Blackberry users. Tag will be coming in BB7 and is the name of the NFC sharing tech RIM has been working on. It’s worth noting that Tag is subject to network certifications. That would mean a chance that Tag is on some networks and not others.
