Right now I have the 9800 & I'm waiting for the 9900 to come out. So I haven't been in a brick & mortar Verizon store in a while. But I've been reading on here about a new UI. Is it standard on all new phone now?? I saw the 9900 pictures and it looked like it had a new blue-themed interface. If anyone has a phone with this UI....can u tell me what are the differences. Advantages....disadvantages??
