Putting an AT&T Sim in Nexus 4 -- Is that HSPA+?

Hello all,

So, I got a Nexus 4 yesterday and slipped into it my AT&T sim from my Galaxy S3. I know I won't be getting LTE connectivity on it, but I just wanted to make sure I am at least getting HSPA+ on it. I see a 'H' in the top right above the signal strength -- is that meaning it's HSPA+?

Also, are the speeds at least decent for it? I'm in NYC, btw.

Thanks, guys!
