I am in Belgium for a couple of hours (I live in Finland) I have an opportunity to buy one of the famous (expensive!) unlocked iPhones. 1) Will it really just work with a normal SIM card? Just put it in and all done? 2) The same question for the GPRS 3) Apparently if I install one of the hardware updates, it will lock the phone down... Is this true? 4) Does this mean that I could never update the software (or that I would be forced to update and then unlock unofficially - and how wasy is this? I would be grateful for some fast reponses as I am very tempted here and have to catch a flight !
