    i found this information there for anypne eho is wondering

    Are YOU one of those people wondering what a rom is? a rom is like an operating system its called a ROM because it installes to the ROM chip on your phones motherboard

    now to the pros and cons of it all
    ___________________________________________________________________

    Reasons you should not install a custom ROM:

    -You will void your warranty. The manufacturer or third-party warranty company will not be willing to repair a damaged phone that has been rooted or has a custom ROM installed. While the ROM may not be the cause of the issue, your warranty will still be voided.

    -During the process of rooting, something may go wrong. You could brick your phone. There are ways to unbrick it, but you could potentially need a new phone. Without your warranty (you just voided it), you will have to pay full retail price for a replacement.

    -Custom ROMs may cause you to experience odd issues. I once used a ROM that would crash every two to three minutes during phone calls. It was extremely frustrating.

    -Custom ROMs update quite frequently to fix bugs. (Sometimes causing more bugs, but that’s another story.) You’ll end up having to update every few days, sometimes even having to wipe your data and restore it later. This can be a good thing, because bugs are getting fixed, but it can also be annoying to have to update that frequently.

    -You may accidentally give a malicious app root access, allowing the app to do whatever it wants to do with your phone. It could potentially wipe all of your data, take your files, including private pictures, and send spam to your contacts.


    why you want it

    Reasons you should install a custom ROM:

    -Kernels: Custom ROMs usually also come with a custom kernel, which gives you many advantages over the stock kernel. For example, ROMs using BobZhome's custom kernel built for IHO can use the cifs module he built with it. This allows you to access your PC via Samba/CIFs file systems using an app called cifs manager. The difference between this and most file browsing methods is that you can use the file as if it were on your phone. So for example, a video file will start to stream from your PC instead of having to transfer over to your phone before playing, and a PDF file will open immediately instead of transferring.

    -Tethering. While this does void your carrier’s terms of service, and I do not recommend doing it without a tethering plan, custom ROMs usually provide you with the ability to tether without a tethering plan. It is often the only reason people want to install a custom ROM. Again, I do not recommend this because you may eventually be caught and your service may be terminated. It is essentially stealing from your carrier. You’d be getting one of its services for free.

    -Battery life improvements. With root access, you have the ability to calibrate your battery, which usually will fix any issues you’re having with battery life. Some custom ROMs also under clock the CPU to reduce battery usage. With my ROM, I get a few more hours of battery life than I had with the stock ROM, and performance is actually better. If battery life improvement is all you’re interested in, I recommend that you try JuiceDefender. It’s an app that manages your wireless connections and disables them when your phone is locked to save battery life. It enables the connections once every 15 minutes so that you can still get notifications.

    -Apps. Some apps require root access. A good example of this is DroidWall, which lets you keep apps from using data while on 3G. This is great if you’re on a limited data plan and getting close to your limit. I’m also a fan of BatteryCalibrator, which is the app I use to calibrate my battery after flashing a new ROM.

    -Over clocking and under clocking. You can use an app, such as SetCPU, to over clock your phone, giving it better performance, but sacrificing battery life. This may be something you want to do if you’re having trouble running a game you really want to play. Some Custom ROMs are already configured to over clock your phone. You may also be interested in under clocking your phone. Under clocking reduces performance but increases battery life.

    -Newer Android versions. I’m excited to try Ice Cream Sandwich, but a release date for this update, for my phone, has not been announced yet.

    I believe that there are more reasons to install a custom ROM than to stick with the stock ROM, but I still don’t recommend it for everyone. You must be willing to deal with getting it set up, backing up all of your apps, restoring them after flashing, calibrating your battery, and updating very frequently.

    Good post, thought I would add a few things:

    Custom ROMs usually also come with a custom kernel, which gives you many advantages over the stock kernel. For example, ROMs using BobZhome's custom kernel built for IHO can use the cifs module he built with it. This allows you to access your PC via Samba/CIFs file systems using an app called cifs manager. The difference between this and most file browsing methods is that you can use the file as if it were on your phone. So for example, a video file will start to stream from your PC instead of having to transfer over to your phone before playing, and a PDF file will open immediately instead of transferring.

    Custom ROMs also offer other features you won't find in stock ROMs such as CM's permissions management, which allows you to allow/deny individual permissions rather than an all or nothing choice. And there's many many more examples.

    And perhaps the single best reason for using a custom ROM: updates. So long as you choose a ROM with an active developer, you can count on updates to make it better and better. ;)

    I used to be big into flashing custom roms, starting back with WinMo, and always tried the latest and greatest. I loved the battery life and performance gains, and the root only apps were pretty wonderful. But there was ALWAYS at least 1 tiny issue for me that has led me to not flash anymore. For instance, a call not coming through, or ringing but not able to pick up, or the alarm would not go off. Sometimes just minuscule issues that would prevent me from using the phone for its intended purpose. And really, I just don't have the time to keep up with it anymore. If I did, I would probably be spending hours flashing and debugging like good old times. I do miss custom roms though.

    +1 for Battery life, Newest versions, and getting rid of OEM custom UI. I never really liked any of the custom UIs too much. Sense is the only one I wouldn't relly mind keeping on my phone but MotoBlur or whatever they call it now, and touchwiz just don't please me. I've always preferred stock.

    I have to disagree with custom ROMs meaning you have to update all the time. When a stable release comes out you flash it with a couple wipes and wait for the next stable. Unless there is some big bug in the last stable the next one doesn't normally come out that quickly. I always used nightlys when I ran CM but that's cuz I'm a flash junkie :D

    The only con I can think of beyond risking your phone is that there will always be some bug the devs are working on. But I don't consider that a con, since you actually have an active dev working on it. On the stock ROMs, if there's a bug, you are stuck with it.

    Another pro from a marketer's point of view, have you noticed how many people with custom ROMs installed have purchased the OV for others at xmas? How many of those same people would have chosen a different phone if they had been stuck with the OV's stock ROM I wonder? ;)

    I was content with the stock rom, but I loath ads. That's the only reason I rooted. I'm more than content with BACKside though.

    A pro: No Carrier IQ and other preinstalled bloatware.

    A con: I have an old bricked G1 sitting on my desk. Yep, it can happen.

    I have a paper weight, but thats because I didn't come here first for advice and direction. It is also the reason I try so hard to keep others from bricking there phone by giving the best instruction and advice I can. I continue to improve my knowledge at all times for this same reason.
    Con: lack of knowledge and experience leads to brick.

    Pro: the proper advice and instruction leads to a customized phone that, for the money, can't be beat.
