The Tools for mobile Linux (TmL)(http://www.eclipse.org/dsdp/tml/) project has been created to address the gap where existing Eclipse projects do not entirely satisfy the needs of developers of native C/C++ applications for mobile devices. Even though the project intends to eventually address the complete application development cycle, the initial scope comprises support to constrution of a device emulator framework, and a simulated end-to-end environment to test enterprise applications.
Dejitun(http://www.habets.pp.se/synscan/programs.php?prog=dejitun) creates a jitter (variance in round-trip time) removing tunnel between hosts to remove the jitter that normally destroys TCP performance. An example of high-jitter connections is mobile Internet such as 3G and GPRS.

Cibyl(http://spel.bth.se/index.php/Cibyl) is a programming environment that allows compiled C programs to execute on J2ME-capable phones. Cibyl uses GCC to compile the C programs to MIPS binaries, and these are then recompiled into Java bytecode. The programs are not parsed during runtime, and Cibyl is therefore relatively well-performing. With Cibyl, games written in C can be ported to J2ME without switching language.

Personal information data like addresses, phone numbers and appointments are
usually distributed over a variety of different devices using different
technologies, from desktop PC to PDA or mobile phone and even pieces of paper.
Ideally all these data would be synchronized and be in a consistent state.
While it is difficult to address the paper problem, for the other cases there
exists software helping with management and synchronisation of data.
The KDE Desktop provides applications for the management of personal information data like KOrganizer, KAB (the KDE Address Book), KNotes and some others. It also provides synchronisation with Palm Pilots via KPilot. What is missing is the mobile phone part. Kandy(http://kandy.kde.org/) provides this.
