One of my pet peeves with some of the SPB apps is their memory footprint.
I don't really have a problem with it's functionality or appearance, just that at least in these cases they are a kitchen sink sort of app.
So, I'm using iLauncher and PhoneWeaver to replicate many of the features I did like from the SPB apps... Both of which I already owned. PhoneWeaver was won here in a contest
There is a trick that I read in the SBSH iLauncher forum to make a iLauncher button list the contents of another iLauncher tab... So I'm making one a speed dial list, another a SMS list, common apps, etc.
The new PhoneWeaver has 3 modes of display now instead of the previous today item, which makes it more flexible.
I did install a freeware app "Call Firewall" to handle the blacklist feature... I'm also considering "Mobile Secretary" But I haven't decided yet.
