I donno bout other countries but in India we have some live chat help option which I clicked to try to find the reason why even though we all got mails saying WP 7.8 is released n all but Zune just has made up its mind that our phones are upto date ...... N the dude says that Zune hasn't got the software update yet . You can go and get ur 710 upgraded at any Nokia Store but U will lose ur data ... I asked him when is it coming on Zune ... He said soon .... N that's all I could get ..... WTH Nokia ? O.o ?
But lets keep our fingers crossed n hope our 710's get thier update soon .... And if anyone does get an update pls do post here bout it . After all we R all in this wait together
