I have a problem with the MFStandardExampleMidlet sample in the SDK 1.1. When I run it on the phone, I get:

No Class Def Found Error java/lang/NoClassDefFoundError com/nokia/nfc/nxp/mfstd/MFStandardException
I think it might be because I have the phone software version 3.12 but I can't find where to get an update (update through GPRS fails).
