I installed the UK version of KIES (PC interface to the Infuse) but the Infuse is not supported. I don't get it, since the manual says it is available. Guess Samsung needs more work on the PC software to make it available on the us download site.
BTW I got the sandisk 32gb microSDHC for 69.99$ from cellphone shop. net. I don't know the class # but I've loaded 2GB of music and the rest of the memory is identified by my infuse.
