Not sure wher to post this, so thought I would try here. I use NEXTEL and have a model I530, the yellow rubber wrapped phone. Supposedly very durable. I have had one die on me already after a year+, sent it in and they gave me a new one. Just replaced the battery because of a consistent shut off problem. THis is after less than a year. We think it is a loose connection, so they had me put a business card between the bat. and the cover. So far so good. But I have ordered a new 870 with camera, video, color screen, Bluetooth, etc. I am concerned about the durablity of using one with all of this "stuff". I do excavation/ landscape construction so on and off machines, shoveling, raking,like we all do. Just curious what you guys think. Thanks for any input.
