Thinknig of using Sprint GS3 on Metro! Questions!! topic

Hi,
I have a Sprint GS3 running 4.3 stock that I am contemplating bringing over the metro. I have a few questions for the experts here:

1. Is there a stock Metro pcs rom that I can load on this phone? Purpose would be to automate things like update PRL button to work for metro, Visual voicemail to work and remove sprint bloatware and use metro bloatware (ha).

2. Phone seems to be fine with talk and text but no data. I have looked at the guides over here but so far, no go. Anyone can help me find out what is my SID??

Thanks
