Research In Motion�s line of BlackBerry smartphones retained British customers better than any other manufacturer�s devices during the three-month period ending in July. Among BlackBerry users in the United Kingdom who purchased new smartphones during that period of time, an impressive 69.9% chose to purchase a new BlackBerry smartphone rather than stray to a new vendor. The impressive stat comes from comScore�s recent MobiLens report, and it bests Apple in the No. 2 spot with a 65.2% retention rate and distant No. 3 HTC at 48.1%. Nokia (33.5%) and Samsung (29.4%) rounded out the top-5, and Sony Ericsson trailed with 22.5% in the No. 6 spot. A graph illustrating manufacturer retention rates in the U.K. over the past three months follows below.
