Nokia's S40 vs. S60: Float Like a Butterfly and Sting Like Java ME

Here's a head-to-head competition of Nokia's Series 40 vs. Series 60 phones by krisse... Because the S60 is multitasking, there's lots more chance for Java ME CDC technology to do some fun stuff on the system level on those phones, like more OS type functions (wrapped in Java calls). Eye of the tiger, baby! I pity the fool! — Hinkmond Wong   (Jun 08, 2007)

Juicy Java ME Enabled RAZR 2 is a JUIX Phone But Still EZX in the Core

The new RAZR 2 is said to have JUIX on it, which from what I've read, is a smaller version of Motorola's Linux/Java software. That should be fine to run a phoneME Advanced stack on top of....Without having to rebuild a new kernel, phoneME Advanced can be built using the OpenEZX header files to link to the EZX or JUIX libs. — Hinkmond Wong   (May 21, 2007)

Isn't Sun the first open source startup? Well, I believe Sun has embraced open standards from the beginning....When Java was released to the public back in 1995, the source came with it. So Java has always been an "open" platform, but now it is FREE... —  Qusay H. Mahmoud

Linux/Java in New RAZR 2 Phones

Some of the new Java ME technology-enabled RAZR 2 cell phones just launched from Motorola will have Linux as the OS. Finally!

Lots of new places to run Java ME CDC (aka phoneME Advanced)!. — Hinkmond Wong   (May 18, 2007)
