iPhone 3.0: Something I've noticed

I, like many technology geeks, am the proud owner of an iPhone 3G. Last night, when I got home from work, I downloaded and installed the latest upgrade for my phone, taking it from 2.2.1 to 3.0. The download was much faster than previous upgrades, and the install was quick and painless. I've had no problems since I upgraded, and have, in fact, had a delightful result. In the building where I work, I'm on the 22nd floor. I'm in the middle of downtown Atlanta, but apparently, the height of my building had been a problem with my connection. Instead of 3G, I was almost always on EDGE while at work. This was very annoying, as I was without a service I had and still was paying for. Today, however, I have yet to drop to an EDGE connection. Not once. I've never had a day before where this happened. It seems that something in the update fixed my connection issues. While I like being able to copy and paste, having a landscape keyboard in most apps, and being able to perform a search from just about anywhere in my phone, I'd have to say keeping a 3G connection is definitely my favorite thing about this upgrade so far.
