Android 2.2 or higher, with phone functionality.
Not extensively tested in different phones.
Network Type Indicator is a status bar icon indicator of the type of mobile network in use (i.e. 2G, 2G+, 3G, ...).

Source code is not public for now.
I'm studying other issues.
If you have a contribution (new ideas, fixes, translations...) to make, please contact me.
