First time flasher!

[delphaeus]

So I'm just about to pull the trigger on flashing my Verizon VX 6900 to the Sprint/HTC ROM posted on the HTC website to enable GPS/etc. I think I've read over most of the material necessary to make this work (don't allow customizations to run).... but wouldn't mind a sanity check from someone who's in the know on here.

-I'm being a bit conservative... really just want GPS to work.
-Currently I have an unlimited data plan and use the GOOD messaging service for corporate e-mail.... any known issues with that app?

Anything else I should know about this process before I get myself in trouble? Recommendations? Maybe any really good/stable ROMS based off this one everyone would recommend?

Only things I really want beyond the above are Google Maps of course, and a good graphing calculator program for my Calc class lol.

Thanks!
