ZTE Blade GPS only works on WiFi, cuts off Mobile Internet

[Guest rossyl]

Hi

Hoping you can help.

My ZTE Blade has Japanese Jellyfish installed.

GPS works fine when connected to WiFi. Connects very quickly when it has WiFi.

But when connected to mobile internet GPS just will not lock. I have tried the GPS status app, reset A-GPS data but still didn't work. Satellites will be found bit will not lock. On turning on GPS the Mobile Data will just stop. No mobile days when GPS is activated.

I'd there any fix at all?

Thanks
