I'm really tempted to buy an iPhone 4, but all the reports about the antenna issue as well as the latest reports on the fragile glass finish have scared me away a bit, to be honest. This would be my first iPhone ever, and since I live outside US I was planning to buy a factory unlocked one, which is quite more expensive than the ATT ones. What would you suggest? Do you think I would have any regrets if I buy it now and not wait for no. 5?
