iphone 4 no service spares or repairs ?

REDUCED!!! This is an Iphone 4 16gb in black, which says NO SERVICE when a sim is inserted. The phone is in warranty until July so could be sent to apple for a replacement. About 9 months old. Can not make or recieve calls but everything else works fine such as wifi, camera etc. Left speaker is not working but as mentioned its still in warranty. The phone should work abroad although this information will need to be double checked The phone is in excellent condition. There is very minimal wear on the back of the phone and the screen is in near perfect condition with a couple of very tiny scuffs but these are barely visible. As this is sold as spares / faulty there will be NO RETURNS accepted, and NO REFUNDS given. This is for phone only - no original box or charger Any questions please message me. Thank you.
