I can't wait for the merger to complete, I live in Southern California and the reception here isn't great. It's not BAD but it's not great either. The data speeds are around 5MBPS (AT&T), which is really good but if the merger happens, hopefully by then AT&T will release faster 4G speeds. I know it won't be useful until an iPhone with 4G comes out, but it would be nice to know there is 4G speeds where I live. T-Mobile has 4G speeds in my city but it's not as fast as I thought it would be. I drove to a store 5 miles from my house and tested it out, it's pretty much the same speed as AT&T's 3G.
I just want everyone to be able to buy an iPhone. That means more people to FaceTime, iMessage, and play multiplayers games with.
But mostly, I'm just tired of my calls being dropped. I don't want to switch to Verizon (like my mom, dad, brother, his girlfriend, my girlfriend...) because I actually DO surf the web while talking on the phone and love the 3G speeds. My AT&T iPhone is 5 times faster than the Verizon iPhones my family has.
The merger NEEDS to happen.
