Your friend phone is locked to particular network so that it shows "Invalid Simcard".He has to unlock it.Then only he can be able to use it with his sim card.For unlocking,you can get unlock code at reasonable cost for Nokia 6680 mobile phone from .
If you have the problems like Gallery files or file manager not displaying,you can better reset the phone.
