AT&T and Java permissions
isw
AT&T-branded SE W580i. I got the phone to find the GPS (thanks, John),
but when I try to get it connected to GpsMid (the mapping app), I get a
message about "connecting to BT not allowed". Further, I am not able to
set up any pointers to directories on my memory stick for storing
tracks, etc. because I get a "permissions not set" error.
I think I now understand (*despite* "help" from AT&T), that the problem
is that AT&T does not allow me to set Java privileges to my liking, even
though it's *my* phone, not theirs.
This seems to have something to do with AT&T wanting to retain control
of what Java apps I am allowed to run, by requiring "certificates" which
are far too expensive for open-source developers to obtain. This, of
course, makes for a cozy relationship with commercial vendors, by
cutting out any possible competition from the FOSS community.
I also think I understand that if I "debrand" the phone (restore it to a
generic SE W580i), AT&T's Java stupidity will no longer be a problem.
Does anyone know for sure that Java permissions can be user-set on an
unbranded, generic phone, even with "unauthorized" Java apps? I'd like
to know before I go to the trouble of debranding it.
Thanks

I think you will find it not an AT&T/branding problem, but a J2ME
signing and/or permissions problem.
On the AT&T-branded Motorola RAZR V3xx, a similar problem (Internet
access) can be worked around with modifying ("modding").

It *is* an AT&T branding problem -- it's the way they have *chosen* to
handle J2ME permissions. Palm devices, for example, have no such problem
with Java apps. Users can adjust permissions to suit themselves.
And I'd still like to know about unbranded/debranded SE phones, if
anyone has any knowledge of them.
