more memory card corruption!!!!

[riironman]

so since there are alot of new roms out there, are there still memory card corruption issues? I am about to take the step. I basically like my stock rom except the damn memory card has been messing up every 2 weeks or less. How close is the merged wm6 and the 6.1 rom to the stock sprint rom? and one more question...will i still lose my msl code on these new roms?
