I am also very curious about this! https://mobile.twitter.com/jeffbenjam/status/642488010974588929 Has Jeff from Idownloadblog and a pretty famous jailbreak dev (one hand wizard) discussing him not wanting the 128gb version because it is TLC and Jeff mentions an anand article. All I can find myself are articles mentioning the regular 6 and 6+.
Should be simple enough for someone with an S model to check. I am deciding between the 64 and 128, so if those who have received their phones could check that would be appreciated.
