Thanks for this thread! It has been very useful... Here are my findings...
Got a Nexus 4. I'm new to ATT. Went into store. They gave me a SIM card and set me up on a Share Everything plan and sent me on my way. Got home, data doesn't work at all. Read this thread, figured out that I have to change my APN settings. Changed to the APN on page 2. Was only averaging 2mbs (which isn't bad). But further reading of this thread, it seems HSPA+ should be average around 8-12mbs. Did the whole "fake IMEI" setup with customer support to make sure I am on the HSPA+ plan. ATT now things I have an Infuse. After checking the status screen I do see that I am getting HSPA+ 15. NOTE: This changes to HSPA 10 when data is idle -- run a speedtest and check the status screen while it's running and you will see HSPA+ 15. After doing the "fake IMEI" I was still only averaging around 2mbs. So I chatted with Customer Support to verify everything was set up correctly. I then asked them what APN I should be using... Here is what he told me:
I'm on an LTE plan and my phone originally came with those settings, but I was getting unbearably slow speeds. The speed test app wouldn't even register anything. I changed to the settings on the second page, and was averaging 5mbps down. The coverage isn't great at home so I'm anxious to test this at work where I get excellent coverage to see what I'm truly capable of here.

Plugged that in... averaging now 4mbs. Twice the APN on the second page. Also ran both APN's through speedtest to verify consistency. This APN was always better. Is anyone finding this APN worthy?
