BEWARE! When it comes to SD card support, there's no such thing as an "Android phone." Each model has its own custom OS with its own custom rules. And, just because your phone has a slot for an SD card doesn't mean the SD card is supported in any meaningful way. Many devices with SD slots deliberately cripple SD card support, preventing you from moving applications there or making the SD card the default for data storage. It's unlikely that you will find out that your phone's SD card support is sodomized until you have already purchased an SD card, installed it ad tried to use it.
