I have unlocked my iPhone 5 that was originally locked to AT&T with the R-Sim 9 Pro. I am currently using T-Mobile as my service carrier and was wondering how I could get network faster than 2G (Edge)? I am on firmware 6.02.00, currently jailbroken as well, but cannot seem to find a solution to my problem. I have read a lot about being able to run LTE through a jailbreak tweak, but that is only for iPhone models A1428. I have the model MD636LL. I purchased the RPatch activation code and that was successful, but still no LTE just Edge. I am wondering if it is even possible to get LTE on this sort of iPhone model, and if not how about 3G?
