Research In Motion: Positive momentum in first 2 months; tgt raised to $57 - UBS (59.71 +2.91) -Update : Earlier, UBS raised their tgt to $57 from $42. Firm says on the whole, firm's checks looking in the past two months indicated positive momentum for RIMM. Firm believes hardware may be tracking toward the higher end of its 7.5-8 mln unit guidance. Feb promotional activity may be a swing factor for subs and Verizon's New Buy 1 BlackBerry, Get 1 Free promotion through March may help to some extent. Regarding Storm, firm's survey of ~50 stores suggests that return rates for Storm were initially higher but levelled off, with Curve the most recommended alternative. Firm's primary concern remains the weak macro environment. M-Flex, a RIMM supplier, which preannounced positively in Jan citing customer demand strength continuing into its current qtr, reversed its outlook last night and indicated "softness in customer orders" "across the board".
