While rumours were circulating about Telstra chucking in more data to their $49 cap plan, Vodafone were polishing their new Infinite cap plans for new and renewing Vodafone customers. Starting at $45 a month, they'll give you unlimited talk and text to any mobile or landline in Australia.
Also included in the Infinite plans are unlimited access to social network sites like Facebook, Twitter and Foursquare (also MySpace, but who still uses that?) The difference between the plans is all in the data - $45 gives you 1GB, $65 has 2GB, the $85 had 3GB and the $100 has 4GB, although you should read the fineprint - there's an additional $0.25 per MB charge for tethering, and charges for accessing voicemail as well. On the upside, each plan comes with a suitable amount of credit included for things like international calls, and they're all available on month to month, 12 month and 24 month contracts.
