As advised by the experts, I did a factory reset when my phone went wacky on me. I didn't actually have Froyo installed when this happened, but as soon as I did the reset, I received a system prompt concerning the available upgrade and took it. My phone works better now, but but battery performance is about the same. I have also been advised that battery performance (as in better than ever), among other things works best with a clean install, not the upgrade. Since I did a factory reset before taking the upgrade, I wonder if this is equivalent to a clean install, or if the clean install would still be worth my effort. If it's the latter, there is only one resource for clean install files which I have been referred to, which cannot help me because I don't have an XP machine available (I did try it on Windows 7). If a clean install is, in any case, the best option, are there any Win7 installation files available for Froyo?
