Vodafone UK has announced a number of plans tailored to unlimited data usage for £5. The actual cap is 500 MB per month so unlimited may be a bit of an overstatement. Typically UK iPhone customers pay from $30 to $70 for 3 GB of data with a two year contract or $40 to $80 for those who do not want that two year contract. Customers are also offered insurance for $10 each month, just in case they go over their monthly allowance.
