Yeah, AT&T does have a limited amount of 3G but hopefully they improve on it. The thing I wonder about this type of data is that both AT&T and Verizon are planning on upgrading to LTE for their 4G networks. But while AT&T should be able to make a more simple upgrade, Verizon will have to make a more vast upgrade. So I wonder if that alone will cause AT&T to have less of a problem expanding 3G now; seeing as when it comes time to upgrade to LTE; their network will already be ready for it. Both Verizon and Sprint didn't have too many problems upgrading from CDMA to EV-DO, because they are part of the same family of products. That is why EV-DO is so vast and WCDMA (HSDPA) is so limited. AT&T on the other hand has had to invest more money, but LTE, at least from what I understand, is just an update to what AT&T has already been building out. So maybe 3G will be where EV-DO is within a year. Hopefully there will be more 3G soon.
And your speeds are faster then I was able to get with Verizon, but they are not too far off. It's just crazy when I think about the data speeds of just a few years ago, compared to now. I just want to see how fast people have gotten their data speeds up to on any networks.
