Tutorial on How to Sign a message on your MetaMask with MEW.

[Bttzed03]

Is there a mobile wallet that support ETH sign message?

MEW already has a mobile version called MEWConnect
Google Play: http://play.google.com/store/apps/details?id=com.myetherwallet.mewconnect
App Store: https://itunes.apple.com/us/app/mewconnect/id1391097156?mt=8

I believe you can also sign message using other mobile wallets like coinomi and imtoken.
