After doing lots of research I came to my conclusion that is: tmobile soft throttles (14-15 Mbps) the fast.t-mobile.com apn which is the default apn on iPhone 5( on both aws and non aws versions). The solution to get the old hspa+ speeds back(20+ Mbps) is to change your cellular data apn to "epc.tmobile.com" and the "LTE optional" to "fast.t-mobile.com". Tmobile is doing this on all their new devices ( htc one and galaxy s4 and iPhone 5). If you did this method please share your results here. I uploaded a screenshot of joe( the guy that originally got LTE to work on unlocked iPhone 5's before the carrier setting were out). I found his comment on tmonews http://www.tmonews.com/2013/05/hacked-t-mobile-carrier-update-boosts-speed-for-iphone-5-1900mhz-refarmed-users/

Same here. I'm getting similar speeds as you.

That's weird on galaxy s4 forum(xda) tmonews, and nexus 4 forum(xda) everyone is reporting fast.t-mobile apn throttles you. I will be doing side by side testing tomorrow on both my aws tmobile iPhone 5's and see how it goes.

Edit: maybe tmobile is only throttling in certain areas like maybe reframed areas?

Btw, I just want to add that I that I did the OTA T-Mobile carrier update when I had received my phone, if that makes any difference.

Well theoretically the carrier update installs the fast.t-mobile apn so that would make it slower
