Up until recently Android phones tended to use SD cards as storage space, while reserving the internal memory for installed programs and personal data. But the HTC Incredible and a few other recent phones are shipping with large amounts of internal storage space which you can use to store music, videos, and other data — and developers are starting to alter their applications to take advantage of that feature.
According to the official doubleTwist Twitter account, the company plans to add support for internal memory to its recently launched music player for Google Android.
I suspect we’ll start to see other apps with support for internal storage soon — particularly media apps like doubleTwist.
