Just got a iPhone 4 32GB which was preinstalled with OS 4.1 I have full signal bars on 3G but despite this I am getting between 0.3 - 0.7 Mbps. This makes it totally useless for VOIP applications such as Skype which is the main reason for purchase. I get the same results whether I am in or outdoors and in a different part of the city. Location is Helsinki, Finland on the Sonera network. I have been gathering data using speedtest.net and Skype always shows (low bandwidth messages). When connected to my router via wi-fi I get just under 30Mbps and voice works perfectly via Skype. When connected via 3G, I can hear the other person clearly but they cannot hear me. Normal voice calls work flawlessly. I am on an 1GB data max speed package which is capped to 0.64mbps when the 1GB allowance is exceeded. I have not exceeded the allowance. Are there any known issues with this problem or is it the provider? I have emailed the network provider /carrier for support. Switching off wi-fi, bluetooth has not improved the performance. Many thanks.
