The iPod Touch has been coming closer and closer to being "an iPhone that doesn't make calls." Apparently, even the marketing folks at Apple even get them confused; check out the iPod Touch photos released by Apple that are complete with a phone app.
The photos have now been taken down by Apple, so this was a fairly obvious Photoshop failure on someone's part. This probably won't stop the rumormongers from speculating whether the iPod Touch will be capable of making phone calls at some point. Next on the list: someone getting an iPod Touch with iPhone guts. Who knows?
