Not sure but it appears they lose interest in updating once newer versions come out.
They choose to shunt all resources at the new stuff.
My HTC incredible does a great job but I'm not sure if thats the sense overlay added to android or what.. but it works great.
Hopefully groupU and the others figured out a way to do it.... last time I checked it wasn't avaiable and all they did is add contacts to "one" contacts....which is not the same as a group.
Let us know if groupU does what you think cause my daughter still runs the droid... I'll tell her about it.
i know this is an old thread, but is there a way yet to put contacts into groups on the Droid yet?
