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/
