By Randy Fabi and Euan Rocha JAKARTA/TORONTO (Reuters) – BlackBerry Ltd launched a low-cost touchscreen device in Jakarta, the Z3, as the embattled smartphone maker looks to revive sales in emerging markets like Indonesia where its once-fervent following has shriveled. The handset, to be presented at a glitzy launch event in the Indonesian capital on Tuesday, is the first in a line of devices being made with FIH Mobile Ltd, a unit of the giant Taiwanese Foxconn Technology Group best known for assembling gadgets like iPhones and iPads for Apple Inc. The success of the handset retailing for less than $200 could well decide the outcome of both BlackBerrys tie-up with the contract manufacturing giant and its own future in smartphones. That says there is still room for BlackBerry in Indonesia,\ said Ryan Lai, market analyst at consultancy IDC. The Z3 is the first phone to be launched by BlackBerry since new Chief Executive John Chen took the helm late last year.
