[HD2 Android SD Development] shamez23:
With an unlocked phone you could experiment with different radio versions.

some people believe that they get better/worse battery life with different radios.

I haven't tried that personnaly but I don't think the effect is big enough to risk bricking my phone. Not that it's a big risk but it is there and the effect of a radio switch seems to be rather erratic. One radio Version works for some, doesn't do anything for others.

So, it's not worth it in my opinion.

I do have an open phone and I use a custom winmo ROM. Therefore I don't have the new 3.14 Radio but the newest Radio I can get, 2.15.soemthing.

They put out new radios for a reason and they test them. That's why I tend to use any update available.

If you like to play and experiment you might do it differently. To me that's too time consuming because you would have to run tests every time to make sure there is a real difference, for better or worse. You can't really trust your feelings here.

I still haven't found an answer to the question of how much and if at all, the winmo ROM influences the behaviour of Android. I just don't know.

There are stable and not so stable Custom ROMs out there. Some of them are better than the provider ROMs but that depends on your personal taste.

If you want to keep using winmo for at least some of the time you could try experimenting and have a look at all the different flavours the cooks at xda and elsewhere offer.

If you only want to use Android from now on and have winmo as a last resort fallback option, stick with your provider ROM. It's a fully working ROM you are used to.

Now about NAND.

I don't use it. Sure it would speed up the booting process, because you wouldn't need to boot up winmo first and then Android. That takes some time, even with a boot manager but since I only reboot my phone when it's absolutely necessary, which isn't often, I can live with the two minutes more per boot.

I don't want to experiment with windows phone 7 and I want to keep winmo as a fallback option. With AmeriCanDroid I've found a SD ROM that works perfectly for me, so why should I change anything? Especially changes that bring the risk of bricking my phone, no matter how slim they are.

As for which NAND ROM is best, you have to find that out for yourself. Tastes are different. Have a look at the active threads on the first page of the NAND section if you are interested.

My overall advice would be:

Stick with your provider winmo build and radio for now. Try AmeriCanDroid.

It's save and you can find out for yourself how it works and what's important to you.

If you don't like it you can always start experimenting but why do it now when the easiest solution may well be the perfect one?

Oh, one more thing. Start reading. Have a look at different threads, at sticky threads and discussions. There is so much information in this forum, so many different opinions. You are better of to decide things for yourself than listen to one person with that persons one point of view. That person may know a lot and may have found the perfect solution for himself but chances are that solution won't work for you. Why would you want to bend to someone elses believe of what's right and what's wrong when you don't have to?
