All the phones say they support only 32GB but I have seen videos of people testing out the 64GB in those phones. So I guess it's all about trial and error.
All I know is that at release, the largest Micro SD card you could buy was 32 GB, so the question really is, was the TB advertised as going to 32GB because that was the current limit with the cards, or is it also hardware/software limited to 32GB? Surely someone out there knows for sure!
TBolt is equipped with micro SDHC port. The SDHC standard max size is 32GB. Sizes above that are covered under the SDXC standard. So sadly we can't make use of it yet.... if ever as the number of upcoming phones lacking micro SD port all together is almost as alarming as the lack of removable batteries. I can't remember seeing any phones with micro SDXC ports.....
