+For more than 19 years, every GSM mobile phone is running a proprietary
+protocol stack on a proprietary operating system on top of equally
+proprietary hardware. Billions of phones have been shipped worldwide,
+running as a black box controlled by the phone maker and/or operator -
+outside the control of the user
+
+Most of those devices have no user-upgradable firmware for the baseband
+processor, and yet those billions of GSM phones are all connected to a public
+network. Their software is complex compiled C code on a CPU without any
+form of memory protection.
+
+Mobile phones have all sort of features that the user would never want. Why
+would he want his phone to reveal its GPS position to the operator? Why
+would he allow the operator to hide from him, if calls are not encrypted?
+
+The only solution is a Free Software / Open Source GSM baseband stack.
+
+OsmocomBB has set out to create this protocol stack.
