So, the iTouch 4G didn't get the iOS 7 upgrade but in theory it can still run on the iTouch 4. It runs on the iPhone 4 which is an iTouch 4 with double the RAM. I know that because of SHSH blobs it couldn't be installed easily but can it somehow be fudged on there? Like getting the iPhone 4 iOS 7 copying all the files via iTools and see where you get.
Note: Ik it's stupid, just asking if it's theoretically possible.
Seems it could be possible with the addition of a 256MB swap file since it boosts RAM up to 512 MB, ik it may slightly shorten the live of the flash memory but chances are that the battery/LCD will die out before the flash does. Overclocking to 950 Mhz (yes it's possible and it doesn't heat up your device) may also make the experience passable for the average user :P
