As I wrote before, I tried to use Ubuntu Personal Package Archive for distributing up to date Gammu, python-gammu and Wammu packages. For first time I failed because I expected it to behave more like OpenSUSE build service than like Debian archives, but I was wrong, so I have to upload different version to each Ubuntu suite.
Well that sounds like a work which should be automated. So I hacked a little shell script, which takes current version from unstable, updates changelog and injects it into my PPA. The hacky script is called deb2ppa. It requires dput to be configured for ppa same way as I have it and maybe has some other tricky dependencies which I do not realize right now.
Anyway you can now use current Wammu/Gammu versions even on older Ubuntu releases if you wish :-). (Well you have to wait till it is rebuild, but I hope it will not take much time.)
