Some italian users report to me that now (march 2014) you don't need send an email to huawei and wait some days for your Bootloader unlock code but you can directly have this code via web here:
Simply scroll down and accet al terms and go to next - choose Y300-0100 model and put your data and submit and you have your unlock code.
I don't try because my Y300 is unlocked till september but some italian users tried and told is working.
Information come directly from Huawei if you send email requesting unlock code and is working for all Huawei smartphone not only for us:
