“Among mobile phones, smartphones are particularly vulnerable because they’re essentially handheld computers. With several gigabytes of storage now common on smartphones, users store a large amount of data and personal information on their devices—from personal photos to sales contacts. That’s why analysts say the biggest threat is losing the device.

“The biggest piece of data people don’t think about is the amount of passwords the browser has stored,” says Eric Ogren, principal analyst at the Ogren Group. “If you can figure out how to get into that, someone loses his phone and—shazam!—you’ve got access to every account. Facebook, email, you name it. You have total authenticated access.””

“GCC, Apple, and LLVM

The story of the compiler is a little more interesting. While Apple uses GNU’s gcc, which has been ported to numerous platforms and is maintained by a large number of volunteers, they are often at odds with the GNU developers. To this day, Apple’s compiler is a rather drastic fork, and gcc proper simply does not target any of Apple’s machines.

Luckily, as is required under the GPL (gcc’s license), Apple publishes the source code for these modifications. They don’t seem to be very good about it, though (I have heard that they never released the source code to Xcode 2.5’s build of gcc, and they seem to believe they can provide source on their own schedule, rather than with the corresponding binaries, which is required by the license).

As an example: they released the code to their iPhone assembler a month late and only after I complained about it. (To be frank, I wouldn’t be surprised at all if Apple ends up on the bad end of a GPL-related lawsuit.)”
