I discovered a security problem when I went to set up international dialling for my 700P this week.

"Here's how it works. You dial a certain toll-free Sprint customer service line (doesn't matter what number you're dialing from), then punch in the cellphone number of a Sprint Wireless subscriber (not necessarily yours). The Sprint voice-bot reads back to you the full name and street address of the accountholder associated with that number. Could be you, could be someone else."
