hi bought nokia n97 off fleabay recently and now its stopped working( as in cant make calls etc), was locked on vodafone but got it unlocked when i bought it, so i could use it on O2! week later saying sim card reg failed etc!looked around on google and this happens when fone is reported lost or stolen! great I've tried contacting seller on ebay but get no reply etc, yes my own stupid fault but is there anything i can do now apart from use it as expensive door stop?? Hope someone can help! Might just have to recycle fone and cut my loses!
