I went over to a friends house last night and he was fortunate enough to receive a new sprint overdrive unit from his new job that he is allowed to use at home and on install jobs. I was very excited to see what this "4g speed" is all about. We are located in raleigh NC and we get nice 4g coverage in our area...in fact, when we turned in the unit, it was connected to a 4g network in a few seconds. We proceeded to go to YouTube and loaded up some videos to see how the transfer speeds were. Well...after repeated slows and stalls in the download of several clips...I decided to try a comparison between the overdrive 4g and my 3GS running mywi over AT&T 3G network. I was blown away by the speed difference on everything i tried streaming or downloading. Att's network blew the sprint 4g away! I was able to stream and load things over twice as fast....i am even able to stream netflix and abc player at full quality without any interruptions... I went online to research and i found that others have compared all of the available mobile networks in the us and AT&T was consistently on top.. I just wanted to share my experience, because i know a lot of people are waiting for this evo 4g to come out and they are probably expecting it to be much faster than their current 3G on AT&T. Well, from my experience, in a fully supported 4g city....the speed difference just isn't there....in fact it is much much slower than AT&T network. Guess i cant complain too much about AT&T anymore....i never really drop any calls and the quality of the network is very good in my area.. I think we'll really see the improvements when lte comes out..
