My upgrade went smoothly but now when using Zen on my 7100g the homescreen shortcuts don't work. (L for calendar, A for Adds. etc.) They worked fine on HK CSL .300. I pulled the batt. but still no shortcuts. I hate that since I use them. I do like the little bracket around the selected icon on the zen theme since I do not list the app. name. I will wait until I use the phone several times to decide if I'm staying with this one or not. Phone call quality and volume are at the top of my list when it comes to an os for my 7100 since I use it on the weekends as a cell phone first and a BB second.
