One of BGR's connects dug around in the iPad file system and once again found confirmation of what we all pretty much take for granted now -- 4th generation iPhone, 4th generation iPod touch, and even 2nd generation iPad models are coming our way!
As a reminder, Apple users a major,minor version number system. So iPhone 2G was 1,1, iPhone 3G was 1,2, and iPhone 3GS was 2,1. Big jumps equal big hardware (i.e. non-cosmetic) changes, and that looks like what we're getting:
Why three new models for the 4th generation iPhone (not iPhone 4G)? We have no idea, but we'll guess GSM this summer, and could the others be Chinese CDMA, and maybe US CDMA (no Verizon rumors. Stop it!)
4th generation iPod touch, likely this September.
iPad was originally iProd 1,1 so it looks like Apple's already got the 2nd generation iPad in the labs for March 2011.
(What IFPGA is we still have no idea).
