I have Evernote 2.6.1 on Dingo PE and on Ermine PE. It runs OK and on ermine I can use camera. However, when I installed it first time on Ermine, my PE got really hot and was losing battery like crazy (was not the case for Dingo). I ended up rebooting, recharging several times. Also went and enabled Airplane mode for all the time. Seems solve the overheat problem. And oddly you can turn wifi on and still be in airplane mode... After that I used Evernote, and wifi and had no problem with overheat. Cannot find apk for ver 3, so haven't tried it.
