Ohio.
But been to NC(fort bragg/fayetteville/sanford), Michigan, Indiana, Kentecky, WV.
Now recently with the I4 i went to indiana had no bars 3g, always says its on 3g, and pulled a massive number 2.6mpbs and 1.87mpbs. and did it with very close results three more times. left that area had 5 bars did another test 1.2mbps and .02mbps.
I've tried resetting all settings, resetting the phone. Nothing.
So its also a OS error in how signal is calculated thought that was fixed awhile back?? And well AT&T sucks LOL.
T-mobile i would normally on average on a 3g connection pull 4-5mbps and 1+mbps. now on Their 4g i would get 6-7mbps and 1.5+mbps. The 4g atrix doesnt even come close to tmobile 3g speeds? I will say t-mobile has gprs in more areas then t-mobile but i never make calls, just text and emails.
