I am looking at buying a iPhone, and I have been checking eBay etc. Thing is, the price of just below £200 is a lot for me, especially for a used product with no warranty. So, I have been wondering wheather I should get a 3G, the only thing really putting me off is that price, but I figure I would probably end up spending the same on a first gen iPhone as I have to top-up £10 a month for the Pay & Go web add-on I would need, but on the 3G you dont need to do that for a whole year, after which I can get whatever new iPhone is out or maybe unlock it (in a year it should be possible, right?) and use a SIM that gives me a good deal (free internet on PAYG in a year?). Anyway, what do you think? I would use the phone mainly for internet (IM for communication generally), and when I do actually use it to communicate like a normal phone I would use texting, and only rarely make phone calls. Thanks in advance for your opinions!
