T-Mobile SIM card trouble / OsmocomBB

Hi Tobias! Regarding the problem with your current German T-Mobile SIM and OsmocomBB: The 0x60 that was received at startup is actually a "waiting time extension" byte. A quick read through the calypso SIM driver by dexter reveals that procedure byte handling is not implemented completely (only in the special case of RUN GSM ALGO). So basically what happens is that the card sends 0x60 to let the reader know that it is alive, but that it needs some more time to respond. The next byte 0x9f was then the first half of the status word. However, due to the incomplete SIM driver, the code thinks 0x60 0x9F is the status word, which of course is unknown. I'm not able to look into fixing this myself right now, but maybe somebody on the list has an interest in looking into the bug.
