sparkfun celluar shield versus official arduino GSM shield

I'm trying to decide which of these to try:

So far I see that sparkfun has a simpler schematic and obviously supports hardware serial communication.

I couldn't tell if official shield requires software serial or not?

Sparkfun schematic is less complicated. But maybe all that extra stuff on official shield is doing useful things :slight_smile:

I'd love to hear any reports or opinions.

I can only tell you that I've tried the Arduino GSM shield and i really liked it.. It worked perfectly :slight_smile: :slight_smile:

But I'm sure that the one from Sparkfun will be good one too...
