And how much is the data add-on on a contract for an Android or iPhone? How much would a calls only plan cost, for the same number of free minutes, compared to the Android or iPhone plans, which include data?

Edit: T-Mobile (German national carrier), the MaxiFlat M (flat rate in T-Mobile and landline networks), costs 29,95€ a month, the CombiFlat M (the same telephone flatrates, plus unlimited data) costs 49,95€ a month. The iPhone equivalent costs a further 10€ a month... So, a tenner a month for Blackberry Email/data isn't much, compared to the 30€ for the iPhone.
