I can't claim warranty since it's "customer induced damage" : needed to insert my sim card into an Ipad. Not willing to lose my micro sim adapter, I put it in the Nexus S without a sim in an tore the pins when taking it out
Moreover, I live in Europe and Samsung has after-sales per region, if not country. they would'nt accept an US purchased handset anyway.
Didn't find any trace of this spare part on any other site but globaldirectpart and it's still showing as "Coming soon"....
