I wanted to use a shorter title for the thread, but I didn't want to draw the ire of the community for thinking that I was giving new info on 2.1 In all seriousness though, with all the threads on 2.1 and related topics....WHEN it is finally officially released from HTC/Sprint and it is available to us, the Hero owners, to download and install on our units (most likely through PC/USB upgrading and not OTA....not that it matters for this question) will it wipe the phone? The reason I am asking is because this is, in fact, a completely new OS and not just an MR patch. I have posed this very question to HTC tech support when asking about another issue and they said that it will not wipe info/settings/etc from the phone. I don't know what to think about that. With my last WinMo phone, when the Sprint Rev A upgrade came out, it blew out everything from the phone and it was a fresh start. When I upgraded my iMac w/ Snow Leopard, it didn't change a thing. With that comparison, I guess I can believe both sides, however, I was curious if anyone on here has a definitive answer through experience that it wouldn't wipe all the info. Hasn't there been a few OS changes already with Android for the earlier phones? I'm sure there's info out there somewhere, but I was hoping to hear it from someone on here. This is kind of a relevant question, because if it is going to require a complete wipe, I have absolutely no reason not to root, since I'd have to go back to stock RUU to get the upgrade, which would require a fresh wipe of the phone. I'll most likely still be rooting this week, however, I'm still curious about what the upgrade to 2.1 is going to require.
