Rooted my phone and installed CM10 ... did some changes to the Network setting (in my case setting it to global) when I tried to change it to default the app will crash and didn't allow me to change it.
I went back to the stock MetroPCS .... EvDo was the only internet signal I was getting.
This is how I got it back
1- Go To

Type your IMEI and get your MetroPCS MSL
2- Dial ##626* and when promted enter your MetroPCS MSL PIN
3- Click Network Select-->Network Mode (and click again on it)
4- Choose CDMA+LTE/EvDo auto
Your Phone should show 4G
Thanks to Gman9831 for many of this solution was from his post here
