Research In Motion on Thursday announced some serious heat in the Europe, the Middle East and Africa (EMEA) region — the BlackBerry maker said it recently added more than a million new subscribers in less than three weeks. “BlackBerry continues momentum across EMEA with 1 Million+ new subscribers added in less than 3 weeks,” RIM posted from its Twitter account. RIM no longer includes subscriber additions or totals in its quarterly earnings reports, but when it last did in the three-month period ending November 2010, the vendor had netted more than 5 million new subscribers for a total of just over 55 million. Last quarter, RIM said it shipped 13.2 million BlackBerry smartphones and 500,000 PlayBook tablets despite a very difficult quarter.
