Research In Motion, the developer of the BlackBerry e-mail device, is picking up new customers in Singapore and Switzerland. The Waterloo, Ontario-based company announced Tuesday a deal with wireless network operator StarHub to make BlackBerry devices available in Singapore. StarHub plans to begin trials for corporate customers next month. The StarHub announcement follows a similar deal announced Monday between RIM and Swiss wireless carrier Swisscom Mobile. Terms of both deals were not disclosed, and pricing has yet to be determined.
