thx for your quick answer,
well, i did my back up before starting to experiment.
anyway it works well except for the mms sending/recieving problem. it starts mms server connection(w/ port n? like u told),but doesn't receive the message. only if i don't change MMS1 on reg. then it will go for native MMS folder.
So if i understood, i should install the cab and only change the(MMS1).
thx for your help.cheers.
