I have been reading through the topic questions about iPhones and have a question.  I know there is a lot of talk about 1st and 2nd gen and that one difference will be that it is 3G capable.  So my question about that is does 3G capable mean that you can go online etc using Vodafone's data usage?  And without 3G the only way of getting internet connection is through WiFi?  Is that correct?  So if you have WiFi then you can get online and check mail, internet etc?
