ok, then it's the 65xx. it's one of the nokia phones.

True and false. j2me uses a form and you have to put stuff into that form.
anyway there are implementations around which fully support AWT. I 
remember a screenshot on a palm with a j2me (it was not jeode) 
implementation and awt.

this is not true. if you have a prepaid card for a telekom mobile phone, 
you will be able to surf and WAP as much as you want to. but access to 
JAR files and access to files loaded from within the JAD file is 
blocked. believe me, it's true. i spent a whole day with non informed 
telekom service clerks on the phone and they all told me the same as you 
do - until i finally reached a guy who told me WAP and java applications 
are not the same - neither are the terms "internet services" and 
"downloading java applications". krass but true.

whenever i renamed the jar file on my server to something else (ie. .JA) 
the file could be downloaded/accessed (but not started, since the jar 
file required to be loaded from a jad file). when i loaded it through 
the jad file i had no entry in my server's log file - try it.
