I am finally getting to use GDE on my Moto Droid and I am loving it!
One of my biggest pet peaves about my phone was not having any hard buttons for the phone and that was one of the reasons i wanted GDE to work so bad with 2.0.
Gotta problem. Eversince the update, i added the widget (4x3) which i love, but when i go into an app (anyone of them) and come back out, the widget is blank and all of my contacts in the messaging app arent there (just puts their phone numbers instead of name)
