This is the speedtest screen capture I did on my brand new iPhone 4S. As you can see, I got .016Mbps down and 0.05Mbps up. For those of you want to say maybe the network is just slow in my area. I did the same test with Samsung Epic Touch with 4G turned off at the same spot. It's 3 times faster. Is sprint crippling iPhone data rate, or there is something wrong with iPhone CDMA radio itself.
I hate to have to post this and sound like one of those OMG SPRINT SUCKS posts since I have enjoyed the service on my Evo. But since the launch I found my iPhone 4s was unusable for data in any consistant manner and the Evo that I was replacing is now worthless as well .
I have returned my iphone and ordered an ATT line. For any who are looking for iPhones in general Radio Shack is sitting on a nice supply .
I will be cancelling my sprint service come Friday when my new phone is delivered. Unlimited Data was good while it lasted but at this point I have resigned to pay for consistant usable speed. GL all and I hope it gets better for you.
