I bought a phone from ebay but the seller doesnt knoe wether its us/uk? I have brought a next sim v4but am having problems using it. apparently it doesnt work with uk ohones. therefore i need to find out wether my phone is us/uk

furthermore is there any way to find out wether it is 1.1.2 otb or not? i have tried using problem but wehn i type cd\usr\bin it "cannot find" the target.
