iFile 2.1.0-1 will be available in Cydia later tonight. Change-log can be found at tinyurl.com/ifile-2-1-0-1.
So, iFile is now supporting iPhone 6 and 6 Plus screen. Icons have been added also in iPhone 6 Plus resolution.
Apple has moved the AppStore apps in /var/mobile to a different folder. That's why iFile does not show the app names. Will fix.
