*I took the plunge and rooted my phone by way of the auto root. I have flashed to cyo7 which I am not a big fan of. Is way of auto root ok? I mean it has worked so far..
I have never heard of auto root. Do you have a link? I am more familiar with Unrevoked for an automated rooting method. If you are rooted and can flash ROMs, then you should be OK
*I love sense! which is the best(smooth, w/ no bumps)
I still like Sense myself, it took me a while to make an AOSP ROM my daily driver. For other Sense ROMs you can try, there are quite a few out there. Popular Sense ROMs are: Myn's Warm TwoPointTwo, Sprint Lovers, and I liked Calkulin's EViO 2.
*I really want to download the sprint lovers rom but you guys now have me second guessing myself b/c of this gps/voicemail issue? should I be worried?
I'm not familiar with any problems with Sprint Lovers ROM. The GPS/Voicemail issue isn't with a Sense based ROM it is with AOSP like the CM7 that you are now running. FYI the GPS issue (if it happens to you) has a fix. It happened to me, I did the fix and haven't had any problems with it since. The Voicemail issue isn't really an issue it is just that the Sprint Visual Voicemail app doesn't work on AOSP ROMs. So, if you use Sprint Visual Voicemail you are affected, but it's not really a big deal in my eyes.
*Also, what are the security risks I should be worried about?
When you root your phone, it is like being the Administrator on a Windows machine. You have complete control. As Peter Parker's Uncle used to say, "With great power comes great responsibility." It is technically possible that you could flash a ROM that has malicious code in it, but most ROM developers are willing to let others see their code so that it can be verified as safe.
I want to thank you guys ahead of time, I have really been wanting to root for a while, I unfortunately like to just dig in w/o reading up a whole lot..LOL
