Thank you, Ezekiel (E2ek1el

! Glad to know "Cache" can be emptied, if even by another name.
Now re those "disappearing bookmarks" in ios6... anyone else?
NP at dude.
What's this disappearing book mark problem on iOS 6 you have? I've looked it up and it seems when this happens ppl would reboot, it appears again and then vanishes.
I haven't had this problem nor have I heard it until you mentioned it. Give this a try, I did this method in iOS 5 a couple of years ago and my bookmarks have been displayed correctly since the first day of iOS 5 Beta 1.
From a Windows Users
1) Del all your bookmarks from Safari, which should be synced with iCloud.
2) Sync with iTunes with your browser
3) Turn on iCloud on the iDevice that you just synced and merge with iCloud. You can also do this with iCloud Control Panel now.
Mac ver (assumption by same theory)
1) turn off iCloud on the iDevices and delete all bookmarks
2) same as above or turn off iCloud syncing from Safari on your Mac and keep the bookmarks
3) turn on iCloud and merge on all iDevice and the Mac
Basically in short, delete all bookmarks and turn off & delete iCloud bookmarks on all devices expect for one. The last device, turn it off and keep the bookmarks. Turn it back on and merge it to your iCloud account, finally turn on all devices and let them all merge and sync the bookmarks.
The reason why the bookmarks are disappearing, it syncing from one source which is iCloud and some devices on your account has a bookmark that hasn't synced proper and its removing during the sync. Same as if you deleted a contact and didn't have web access, once you get access again it syncs corresponding to what your command was before when you're offline.
