Oops. It looks like the three music-centric handsets Nokia had in store for the world at an event tomorrow are slipping free a bit early. Seemingly taking a cue from RIM’s naming conventions for BlackBerry devices, these three brothers will do their best to confuse you. First up we have the entry-level 5030 XpressMusic, a candy bar with a crazy speaker on the back, an integrated FM transmitter and no camera. The battery is said to last for 24 hours of music playback and will hit the streets next quarter for a remarkably affordable €40 ($51). Next up is the 5330 XpressMusic, a stylish slider that also features 24 hours of music playback on a single charge. It sports some kind of lighting effects, a 3.5mm audio jack and dedicated multimedia keys. The 5330 will drop some time in Q3 for €160 ($203). Last up, the QWERTY sliding 5730 XpressMusic pictured above. This guy features a 3.2 megapixel camera, Wi-Fi, integrated GPS and special Ovi integration on the home screen. Like the 5030, the 5730 will be released some time in Q2 and it’ll run you €280 ($366). Hit the jump for shots of the 5330 followed by the 5030.
