Metropcs flash Iphone 4 Vzw or sprint 6.1.2 software

[w4life]

So i flashed an iph4(sprint and verizion) and both of them had an issue with text messaging. when i send the text it barely starts sending and gives me an exclamation mark error. i did the redsn0w jailbreaks, boot tethered, and installed open ssh as instructions said. on the sprint iphone after writing everything using the iphonecdmatool and disconnecting it, the network resets and phone kicks back to saying sprint for carrier and the sprint prl. only way i got it to stick was unplugging the phone manually after writing everything not clicking the disconnect button, and even then carrier would kick back to sprint but talk and web was working but sms and mms didnt work. i tried another method through cydia, downloading comm center patch from a different source. doing it that way got me to the same point where talk and web working but no sms and mms. on the verizon iphone same thing.

any ideas or help is greatly appreciated.
