    If I had to guess which of the 3 phones you still use I would say it's the Nexus 4. You seem electronic savvy, thus I assume you're smart enough to not have an iPhone anymore.

    No I haven't gotten any data speed above Edge yet with my T-Mobile SIM card. Also the Internet sharing works right after flashing, but after using it a time or two the message to contact the carrier to add sharing pops up. I tried the trick of installing another keyboard language, and then it works again for a bit, then the message comes back. Sometime soon I plan to flash back to the AT&T ROM and see if I can get 4G with my T-Mobile SIM. Maybe I need a US based ROM? I have no clue.

    I also have a SIM unlocked 521 (T-Mobile) and I get 4G with AT&T on that phone. I'm officially confused! Maybe someone with more knowledge on the radios can explain it for me. Here's what I get:

    AT&T Lumia 520 (SIM unlocked):

    AT&T: 4G
    T-Mobile: Edge

    T-Mobile Lumia 521 (SIM unlocked):

    T-Mobile: 4G
    AT&T: 4G

    I'm learning a lot about flashing ROMs, and it's lots of fun! And if I end up bricking the 520 I'm only out $90.02.
