"Apple is returning to letting customers buy the iPhone without a contract, a leaked memo may have confirmed today. Those willing to buy an iPhone 3G or 3GS at full price will purportedly have the freedom to do so at a US store without having a new or existing AT&T plan. The sales would discourage bootleggers only by keeping the phones locked to AT&T and one phone per day.While the memo obtained by Gizmodo hasn't been publicly confirmed by Apple, customers have heard the same from Apple store staff and suggest the strategy is in full effect. Pricing would start at $499 for the 8GB iPhone 3G and climb to $599 and $699 for the 16GB and 32GB iPhone 3GS models."
