Most iPhone apps represent a potential privacy threat, a group of IT specialists claims. pskl.us notes that out of a collection 57 apps, taken from the App Store's Top Free and Most Popular categories, 68 percent were found to be sending UDIDs -- Unique Device Identifiers -- to servers under the developer's control each time they launch. 18 percent of the apps encrypted their data, making it unclear what they were sending. Only 14 percent of apps appeared to be completely innocuous.
