My uncle and I are trying to get some information to help with his and his wife's iPhone 4's. Could you guys post speed test results that you get DURING A PHONE CALL. Please do not post speed test results that are not during a phone call as this data will not very helpful. What we are trying to find out is how other people's data speeds are being impacted DURING a call. Thanks for your help guys. Note: When you post your speeds, please state your firmware version and baseband. Also if it is an iPhone 4 or 4s.
