ATT Unlocked iPhone 4S - can only get 2G (EDGE) on Walmart Family Mobile (T-Mobile MVNO) - Help Needed
The phone was officially unlocked from ATT.
I am in Richmond VA (23233) and there are only some spots where I can get 3G and rarely 4G. Always get EDGE at my work location.
I am aware of the fact that Tmobile is re-farming their network to support 1900mhz phones, but is there any other workaround that can be applied to get at least 3G speeds in my area where I always get EDGE?
I am open to trying jailbreak, if required.
