Yes I have os .148. When I purchased it though it conveniently did not come with os .148 it had the previous version. So I had to go home and do it. When  I went to do that The phone froze up after being an hour and a half into the download. As for customer service If I had the iphone I would not have to go to at&t. I would be able to go to apple. And as a mac owner my experience from customer service was very good. I had no problems, complaints anything. Plus I doubt i'd be in as much as I'm in verizon for my storm. Plus I actually have gotten to know my service rep. But he recently is getting tired of me. He is able to predict the time of my next visit, and as I smile on my way out the door I know he's right.
