For browsing directly on your mobile device (EnV Touch, Blackberry/Smartphone) there is NO 5GB cap. It is in fact truly unlimited. Besides 5GB is incredibly difficult to reach on a mobile device. More than likely you'll never even break 3GB.
Yeah I do agree to the fact 5GB is difficult to reach on a mobile phone... (specially since my phone is a battery devil when the EVDO starts transmitting data >_>).
Well the fact that mobile browsing does not have a 5GB cap is a relief to me since that is one less thing to worry abou since I'll never know if I get too addicted to internet browsing and vcast.
Thank you for your answer.
