Currently in Japan Softbank gives away the 8GB model of the iPhone for free, until end of May. Now this is a really good deal. What I am wondering is, will there be a big upgrade in the new iPhone version? Many speculate this $0 move is to get rid of the old iPhone before the new ones hit the stores somewhere around June. So is it a good idea to get one now or will I regret when the new one comes in? What kind of new features can I expect in the new version? Thank you.
