For the first time, RIM's BlackBerry cornered 10% of US cell phone sales in the second quarter in a market that grew more than 5% despite economic concerns.
A Reuters report, quoting research firm Strategy Analytics, also said Canada's RIM was seeing huge success with both consumer and enterprise handsets in the US where total mobile phone shipments rose 5.3% to 41.9 million units from 39.8 million in the second quarter of 2007.
Also in the second quarter Motorola managed to keep the lead in its home market.
While some analysts have been expecting Motorola to be overtaken by rivals even in its strongest market the phone maker had better-than-expected US sales in the quarter, giving it 25.8% of the US market compared with its global share of less than 10%, the Reuters report said.
Motorola barely squeaked ahead of LG Electronics to keep its global No. 3 ranking in the second quarter. It has been losing market share to rivals such as Nokia and Samsung Electronics for well over a year amid criticism of its handset line-up and a lack of phones with high-speed web links.
