Hi. I'm in the UK. Just got my note 10.1 and I want to buy a 64gb sdxc card for it. I've read a few posts about compatibility with certain firmware (software?) versions. My version is 4.0.4 and Build No is IMM76D.N8010XXALGC It seems to be offering me an update but I'm wondering if it will support the 64gb card now but I'll lose that support if I upgrade. So I wonder whether to update now or wait for Gellybean. Any views? Thanks.
