Hello, I'm going to buy a LG Optimus 3D from www.expansys.co.uk but there isn't any information about guarantee. For how many months I will have guarantee for this phone if I buy it? Second think... i understand that this phone is sim free and it will works at any gsm network,right? Im wondering where this guarantee is accept. If I buy smartphone from www.expansys.co.uk the guarantee it works only in UK or maby in another EU country as well? what about lenguage, can I choose polish language in option of this Lg Optimus 3D?
