I have an O2 micro sim for data and i have sync'ed with itunes so the 02 software has been installed. However, its a just incase thing, I dont intend to use 3G at all unless im in a spot where i absolutely need web access & there is no wifi around. Questions 1, If i want to use the unlimited BT Openzone & The Cloud i guess i will have to buy £2 / 500mb regardless of whether i need it just so the sim is registered and so will be recognised at the wifi spots. True? I think so but pls confirm. 2, If i dont sign up now but later need 3G access but with no wifi will i be able to register the sim at that point? Im thinking i should just buy £2 so everything is setup ..... yes? Thanks.
