Hey everyone! I just wanted to share some observations I've made regarding some data speeds.
When I transititioned here in WY on 5/11, one of the first things I did was performed a speed test. What I was seeing wasn't impressive (1 Mbps or less on download), what was more concerning was in big cities like Denver and Atlanta, I was seeing the same sort of low speeds.
I chocked this up to a burdened network and thought much of it. Now recently I transitioned to an iPhone 4 and instead of cutting down my SIM card, I received a new one from the folks at the local corporate store. It was much to my surprise when I ran another speed test and saw significantly higher speeds (now an average download of 3.5 Mbps/ upload of 2 Mbps) - now I thought this might be thanks to upgraded backhaul, but running speed tests on the rest of my devices (HTC Aria, Samsung Focus) show the same slower speeds.
So if one of your complaints has been slower speeds, take your phone in to your local corporate store and ask them for a replacement SIM. It seems to have made a huge difference for me and it's made me like AT&T all the more.
