you can not install my method with out unlock and S-off. are you never reserved Official ICS OTA update?
any way if you like unlock and S-OFF ur device ? then you can install ICS 1st you want to unlock your boot loader from htcdev and then downgrade your Hboot to 1.49.0007. after install above GB ROM and then update to ICS
No I have not had option to update yet, I was hoping it may come in next few days but nothing.
Do you have a link to do this unlock and s-off please, is it difficult?
