Research In Motion unveiled two new versions of its touchscreen BlackBerry Torch on Wednesday as it seeks to regain ground it has lost to Apple and Google with powerful consumer-friendly models.
Investors reacted favourably, pushing RIM's deflated stock price up more than 5 percent.
But some analysts were sceptical, given delays leading up to this launch. They said a radically new software package due next year would be RIM's big test.
The new Torch models include an all-touch version that mimics the popular style of Apple's iPhone and most Android devices.
Along with a previously announced upgrade to its workhorse Bold model, they are part of what the Canadian company called the biggest global launch in its history.
