The PlayStation Network has added 3 million new customers since hackers brought it down earlier this year, CNET reports. Speaking at the IFA conference in Berlin, Sony CEO Howard Stringer proclaimed the PSN "more secure and better than ever." "We are aggressively expanding its content," he said. "We have more than 3 million new customers since the network came back online, and sales are exceeding what we had before the cyber-attacks." "This year, we at Sony have been flooded, we've been flattened, we've been hacked, we've been singed. But the summer of our discontent is behind us." Stringer also revealed launch information for Sony's Tablet S device, which will be priced at $499 and $599 at launch - the same as Apple's market-leading iPad. The PlayStation Network was taken offline in April this year. Service did not resume for several weeks, costing Sony an estimated $170 million.
