It looks as if the Orange San Francisco II, the surprise smartphone release from mobile operator ZTE, is actually made by Chinese firm (ed: T-Mobile is also selling the handset as the Vivacity).
Florin from UnwiredView reported that the handset appeared on the Bluetooth SIG page as the Blade S; given that the San Francisco was known as the Blade, it wouldn't surprise us if the San Francisco II is known as the Blade S.
The Orange San Francisco II has almost the same specs as the ZTE Skate, except for a smaller price tag and a smaller screen.
It comes with a Qualcomm MSM7227 chipset clocked at 800MHz, with 512MB RAM, a 3.5-inch WVGA capacitive touchscreen display, a five megapixel camera with LED flash and a front-facing camera, Wi-Fi, HSDPA, GPS and a microSD card.
Orange is offering the San Francisco II for a mere £99.99 on PAYG. We're not sure whether the phone can be unlocked already, but given how popular the original San Francisco was (with more than two million units sold), the OSF II with the updated hardware is likely to be just as popular.
The OSF II costs only £10 or so more compared to the old OSF, which makes it a tantalising purchase.
