Can 3520 firmware be modded for 3500?

Could really do with the faster RW speeds so be nice if it was possible for the new firmware to be put on a 3500 (bit like the dl support for the 2500).

Anyone know yet whether it is even possible or whether the drive physically cannot do the faster rw speeds properly?

no, and dont try too flash your 3500 with 3520 firmware, they are not compatible
