Newbie - so be gentle with me!! Suspect this has been covered many times before, but I'm so useless I can't find it Anyway, I have an iPhone 3gs with O2. Am off to Florida for three weeks shortly and can't face the prospect of being out of touch with good ole blighty So, what are the options? Ideally, I'd like to buy a data only deal when over there and just go with that. Quite happy to unlock the phone - not done so yet, but O2 do this quite quickly if you ask them I believe. Don't really need voice or text, but does a data only plan exist and if so where? Am also basing my idea on the premise that to use my O2 sim over there would probably bankrupt me on my return!! Any help welcomed, thanks in advance.
