Not convinced by yesterday’s Blackberry Bold 9900 release date leak? We’ve got yet another document confirming the very same thing but with one extra bit of information: a $299.99 after $50 MIR rebate. The Blackberry Bold 9900 will be T-Mobile’s first 4G Blackberry with HSPA+ capability up to 14.4Mbps. Sounds good Blackberry fans? We thought so…peak the rest of the doc for more information on things we mostly already knew. Me..I’ll just staring lovingly at the “4G” symbol.
