Do you think iPhone 4 will still be sold unlocked from Apple after iPhone 5 launches? I'm thinking about buying the unlocked 4 (won't be able to buy one until the end of August) and pairing it with a PAYG plan to save money over the long-term. It's damn-near $2,000 for 24 months of service with AT&T's least-expensive iPhone plan. Only $1,200 for the same amount of time with the PAYG plan. Of course, the trade-off is no data plan. But I have wifi wherever I frequently am located. Thoughts?
