There are many rumors of the iPhone becoming even thinner, with a tapered design and back matching that of the iPad 2 and iPod Touch. Now there are rumors of 3G capable iPod Touches ("iTouch"). If the iTouch has 3G, why would anyone bother with an iPhone? While claims of 3G iTouches have said that it would only use data and not voice, surely, minutes and texting are going to be "converted" to data type services by even carriers in the near future anyways (i.e. buy only data, no more buying minutes+texts+data), as they are already by third parties like Skype, Whatsapp, iMessage, ect. Could this be the year we see only an iPhone or only an iTouch, or even a re-branding of the iOS mobile line altogether? In the past, the only reason we had separate devices was mainly because the phone hardware was battery and space consuming, thus it didn't make as an ideal iPod as it didn't have much storage. However, with iCloud, that problem (in Apple's eyes at least) is eliminated. And Battery technology is getting better quickly and that's not forgetting Apple's battery life optimization. Thoughts?
