Thanks mauron85!
I just put these lines in xterm, right?
touch /etc/init.d/imhere-0.3.uninstall
apt-get remove --purge imhere-0.3
And..is the name "version sensitive"? I mean, I've got 0.3.1 version.

Actually I analyzed imhere-0.3_0.3-1maemo0_armel.deb, which I guess is version 0.3.1 (as name suggest).

I've updated previous post for uninstall instructions (just added killall command).

Thanks for your help, mauron85!
I've installed it from the app manager.
Here's the result I got when I did the commands as per your post:

There are two file in repository:
http://repository.maemo.org/extras-d.../i/imhere-0.3/

I've analyzed imhere-0.3_0.3-1maemo0_armel.deb (package version: 0.3-1maemo0), but as use see in dpkg output you have imhere-0.3_0.3.1-1maemo0_armel.deb (package version: 0.3.1-1maemo0).
According to dpkg output the package name is imhere-0.3 for both version, which means the apt-get remove imhere-0.3 will work no matter which version of those you have.

Edit: The uninstallation procedure should be same for both version as they are checking for presence of same /etc/init.d/imhere-0.3.uninstall file.

So again invoke following commands:

Exactly the same error message.
Also tried to update it (found it hanging in the app manager updates) and to repeat the steps all over again - same result.
Strange((
Think a downgrade might help?

I hope someone can help ...
I set this app up and set
the first password to be password1
the second one to be password2
the third one to be password3

i then sent a message saying password1
the config menu appeared again and i clicked through it

i then send another message saying password2 to activate sms only
then i sent password1
then i sent config (config menu did not appear)
then i sent numerous password1, password2 and password3 and i cant get the config menu up and i cant un install from menu (yes i did untick the box for it in config)

i want to get the config box back up, tick the box so i can uninstall then try again one day when i have more time ....any ideas anyone?

I think that the last version includes a bug, the bug is, if you enter config menu and you don't explicitly configure a password for "config" it will not be set, even if it's not the 1st time you access the config menu.
I don't know ho to help you,, you need the maintainer (;

Reeby you can also try:
Also on traditional linux dpkg (and hopefully also on N900) there is option to delete pre-remove scripts which can be found in /var/lib/dpkg/info. I guess you should be looking for something like imhere-0.3.prerm and imhere-0.3.postinst.

Before proceeding with dpkg remove/purge post here result of:
For uninstall:

Use at your own risk. I'm not sure if maemo version supports force-remove-reinstreq switch.

mauron85, here is the result of the command (I'll wait for your reply to go any furher. Thanks again for your help!)

Ok. This is the file I have analyzed yesterday. It's pre-remove script, which is invoked just before removing the package itselft. You don't have to be a programmer to understand what's inside. Basicaly it's just check for presence of file defined in $UNINSTALL_NAME variable (the old famous /etc/init.d/imhere-0.3.uninstall file :-)

If it not exists then exit 1 - which means failure = error code(1). You already seen this error: E: Sub-process /usr/bin/dpkg returned an error code (1).
As result uninstallation will fail. If that file exists than packages should be uninstalled normaly (my case).

This was just boring introduction how deb(s) works. I don't understand why you cannot uninstall package the way I mentioned before, anyway you can try at you risk.

Probably it would be good idea to kill process imhere-0.3 before:
