New features were introduced including a removable 3.7v 1500 mAh battery, a miniSD slot capable of up to 2 GB of flash memory storage, a 1.3-megapixel camera capable of 1280 x 1024 resolution, an improvement from the sub-megapixel VGA 640 x 480 camera, and a built-in 1/16" audio jack for the newly included MP3 playback software. The MiniUSB functionality was changed from allowing access to the Hiptop's internal communications to only allowing access to the MiniSD card over a USB v1.1 port. The built-in storage allows for end-users to store files for .mp3, .wav, and .aac playback, camera, user customizable themes and other catalog application's uses.
