Well i know im a bit late on the news with microsoft replacing fautly xbox's but, i have some questions which i cant find the answers for so i hope some of you could give me so help.

#1 When was the update that started some xbox's to go faulty? or has the update not come out yet?

#2 Does this error occur in only a select few models or is it more generalized?

#3 When will microsoft be issuing new xboxs?

#4 There is also talk of an update which some people have, which im assuming they are from USA, do you know when it will be released in the UK?

Thanks in advance
