[ApK]

K3's browser is actually a lot better for Content Server, I use that from time to time (but use the wifi email from Calibre more.)

But Gmail, for whatever reason, insists on trying to open EVERYTHING in a new window on the K3, which, unless hacked, the K3 can't handle at all.

On the K2, links worked more directly.

For example, on the K2, I could click on a JPG attachment in a Gmail message and get a full screen view in the Kindle's picture viewer. On the K3, I cannot get to the jpg without skweezer, I can only see the inline thumbnail.

The 3G downloading from gmail attachments is certainly not ideal, but I was in fact able to figure it out last week while waiting for them to close the airplane doors and managed to get my book from the Amazon email message before being told to turn off all devices.
After that, I bookmarked skweezer.com so it will be slightly easier in the future, but I haven't had the need to do it again yet.

Still, nice to know it can be done.
