3G shield library needed

i need a library for my new 3g shield to run this shield. Is GPRS library is enough for 3G shield or it needs a another library.i have tried IDE's build it exaple's for gsm shield....in GPRS conectivity checking its showing not connected/ERROR.

I have had the same error with the FONA 3G SIM5320E not returning a [l] lat and long co-ords. Did you find a fix? I've got the latest libraries.

@valentm

Have you asked the vendor who supplied the device?
