Cricket Flash on a Sprint phone

[Bigstew33]

Tomorrow I am going to have my Sprint phone flashed to work on the Cricket network. I just need to understand something. Once this is done is it written to the hardware? If I remove and install the OS several times am I going to have to go and pay to have Cricket flashed on it again? $85 is steep. Right now I am using the DCD ROM, but I may try newer roms in the future. Is there a way I can do this myself? Also will this flash allow the GPS, MMS, and internet work?

Thanks
