SEUS updates both, firmware and...sometime CID too.

Update FW is always a good thing for your phone, because often it solves problems\bugs.

If it also updates CID then it's something bad, because it prevents u by customize your phone.

It's a question of evaluating things, or almost, to get information about what a certain kind of update will do.

Anyway as soon as SEUS updates CIDs, hackers starts working on a way to get rid of it, so don't worry either.

When guys of XS++ will release new version, a lot of questions will have a reply.

Bye.
