two questions:

1) How to retain user/server/settings information when updating existing
software in phone? (i even tried to read manuals without luck) Every
time the client is broken (2nd question) in phone i'll have to install
it again and again fill all the info in settings. Or am i doing
something wrong? What is the proper way to install clientshell to phone.
Or is there a utility (free) that these settings could be sended as sms
or with the package to phone?

2) Is anyone experiencing next thing: Client software gets somehow
broken in phone (appt. start to get 2hr shifts, it doesn't sync, some
appt. are not syncing etc.) and only way to fix these is eventually to
install sw again. There is no difference weather it is installed to
phone or memorycard.
