Hey there Podsnap, TheWeeBear is correct in saying that most of the UK carriers are pushing "a" Mango update, some are still not officially stating they are giving a 100% yes to deployment, whether you get it via force method or by being one of the lucky people to get it officially you will find that in many cases especially when it comes to samsung phones and the omnia 7 in particular that the FW may not be updated, this may be due to a particular carrier not having it as part of their mango deployment, there are ways to force the FW update but I would say do not bother until your carrier gives an official word on the status of your phones mango update, you can also try contact Samsung and find out whats going on.
