IPhone Safari running real slow so I found something to do to increase speeds. And found a free app to test before and after. Did the repairs phone on and off no difference. I checked out app and saw I could chose my local tower or one 188 miles away. I used the further tower and ran test again. It was 10000kb faster on downloads and only 400 on the other. If I leave the app as is will my phone stick with the faster tower? Sounds silly but I tried same test 4 times same results.
