mobile-phones, java, developmentI'm searching for a new phone, after my last one (a samsung J700) was lost to a tragic incident involving a washing machine and dryer.
Ideally, I'd like to be able to write java applets, and run them on my new (currently) unbought phone. However, no phone vendors seem to be very good at specifying java support.
Is there a master list somewhere of all phones that support Java development?
[UPDATE]: Have you looked into the Nokia phones, the ones that aren't Android based. I'm pretty sure they ran some variant of Linux and were supposedly more open than Android phones. Also you could try OpenMoko. If OpenMoko doesn't support it probably no phone will. But if OpenMoko doesn't support it there is also a chance you could get a java compiler to work on it. OpenMoko is *.nix based.

For Android I think I found your answer here:
Android does not support J2ME out of the box. Strictly speaking, you will not be able to run Java applications written for other mobile platforms (devices not based on Android).
Android is basically an alternative to J2ME, a rewrite. Most people seem to agree that Android is much more powerful alternative. Android already has a more active community and there is already a lot of useful libraries incorporated in it, which are missing from J2ME.
So if you have a J2ME application that you want to run on Android device, you want to port the code to make best use of Android API features and achieve best performance.
Alternatively you can look into "J2ME for Android" adapters written by someone else. Not sure if there is any production quality adapters out there or if Google will ever create a decent adapter or emulator for J2ME applications.
One such tool you can try is called J2Android.
For other phones I think support is just as sparing.
The Nokia phones with Series 40 can run Java applets.
That referenced page contains 177 Series 40 Nokia phone models:

It is not easy to find a place to start from in order to write Java applets, but I believe the central place for Nokia Series 40 is: http://www.forum.nokia.com/Develop/Java/
Applets, in Java terminology at least, are a (browser-based) desktop technology. For phone development, assuming you mean JavaME, you would be writing MIDlets, which are considerably more constrained in what they can do. There are also various JavaME profiles and JSRs meaning that different devices have different capabilities. However, anything that runs Symbian Series 40 or Series 60 should have some level of JavaME support.
The Android platform is much closer to desktop Java than JavaME is and, so far, not nearly as fragmented.
