Fixing a Lg Optimus T running on MIUI

I just used the miui rom for my lg optimus t (p509) it changed it to a p500 and for whatever reason my vpn dissapeared or apn (whichever is for calling and 3g) It dissapeared and when i try to add a new one which will not save.
I checked the kernel because i thought that may be the problem and it says that the kernel is still flashed for the old cyanogen 10 mod on my p509. Before i flashed to miui my internet and texting worked fine. Any help would seriously be appreciated!
(If it is a kernel problem please leave a link to one for me)
oh and also if there is a way to change the lockscreen slider could also leave a way for me to chane it would be nice
