Barcelona Spain is the hot bed for SDHC cards today. SanDisk announced the first 4GB Micro Secure Digital High Capacity flash card. Now your phone can hold more then 1,000 songs or 2,000 high-res photos (although useless on a phone display) or 8 hours of MPEG 4 video. BUT, before you rush out and grab those extra bytes be sure to understand that microSDHC is not backward compatible with microSD. This goes for both mobile devices and card readers. GetFlashMemory.info couldn’t secure pricing but will post an update when available.
