As the iPhone sprints ahead, word reaches us that BlackBerry’s having trouble perfecting the touchscreen interface for use in the new BlackBerry Thunder.

According to Nomura analyst Richard Windsor, Research In Motion (RIM) is struggling with the final stages of the software’s development.

“Those who have handled prototypes complain of poor typing, unresponsive keys, bugs in the user interface caused by touch as well as accelerometer issues,” he explained to MarketWatch.

Elsewhere, Changewave Research says Apple’s iPhone 3G will act as a “tsunami” of change on other mobile manufacturers.
