WebOS (The operating system of the Palm Pre and Palm Pixi phones) has a built-in messaging application but unfortunately it only supports Google Talk and AIM out of the box. It's a shame that Palm has not enabled more protocols and especially generic XMPP support. The used library (libpurple) supports everything so it's only missing in the GUI.
Google Talk uses XMPP so in theory it should work with any other XMPP server but unfortunately Palm has put this nasty code in the LibpurpleAdapter (which is used as a connector between the GUI and the low-level libpurple):
if (strcmp(prplProtocolId, "prpl-jabber") == 0
&& g_str_has_suffix(transportFriendlyUserName, "@gmail.com") == FALSE
&& g_str_has_suffix(transportFriendlyUserName, "@googlemail.com") == FALSE)
{
// Special case for gmail... don't try to connect to mydomain.com if the
// username is me@mydomain.com. They might not have
// setup the SRV record. Always connect to gmail.
purple_account_set_string(account, "connect_server", "talk.google.com");
}
This code means: If the protocol is Jabber (XMPP) and the entered username does NOT end with @gmail.com or @googlemail.com then the XMPP server is hardcoded to talk.google.com. So if you enter a username like johndoe@jabber.org then the Messaging app does not connect to jabber.org but instead it connects to talk.google.com because of the above code. So we must get rid of this code somehow.
With some knowledge about assembler you might be able to toggle some logic in the binary so the above if statement always evaluates to false but there is a much easier solution. You just need to replace the string "connect_server" with some invalid string. I use "nonnect_server". The result is that the line simply sets some unused property and therefore simply does nothing. But let me describe step by step:

Ich bin kein Mitglied der Softair-Szene, ich habe lediglich eine etwas
professionellere Erbsenpistole gesucht und gefunden. Daher ist
diese Seite nicht als Beurteilung der USP anzusehen, denn ich kann keinerlei
Vergleiche zu anderen Softair-Waffen anstellen. Diese Seite dient lediglich
als Informationsseite zur jugendfreien Version der USP, da ich meine, dass
sowas im Netz fehlt. Denn ich habe bei meiner Suche nur recht wenig
Informationen über diese Pistole finden können. Vielleicht ist diese Seite
daher nützlich für so manch anderen, vielleicht aber auch nicht. Mir doch
egal.
