I have generated a wallet that starts with "3" on electrum 3.0.5 so basically that means Segwit has been enabled right? Will adopt and go for the changes after your announcement regarding the update of our addresses. I'm still figuring it out on how to generate that "bc1" wallet (bech32 address) w/ electrum.
No, not all P2SH addresses are segwit addresses (P2SH-P2WPKH).
Switching to a bech32 address would be pretty easy for me, yet I don't want to do that without asking you guys for your opinion and giving you enough preparation time.
After all, things are supposed to go smooth for both sides, not just me.
