So the "not enough space" message when updating is a bug right?

[felixen]

I have 6.6 GB free space on my iPad air but I keep getting this damn message. If I connect to iTunes and try to update from there it says I alrwady have the latest version (probably because I have the beta installed, but still sucks it can't recognize that I don't have the final 8.0).

Anyone else having trouble installing iOS 8 even with so much free space?

It needs nearly 7GB to install on an iPad.

Though the iOS 8 update was just over 1 GB in size, it required 4.6 GB of free storage space on an iPhone and almost 7 GB of free storage on an iPad for installation.
