Ok, I'm looking to root my phone and I've been lurking a bit, reading instructions and researching the proposed OTA. I'm new to this, but not phone hacks, tweaks in general so I understand almost everything. I have just a couple small questions, largely about unrooting. From what I have read (and I apologize if there was a thread with a definite answer). Unrooting can only return the phone to stock purchase correct? There is no way to just remove SU abilities and Boot recoveries to previous state? I'm going to use Unrevoked, now I have Leopard Win 7 and Ubuntu 10.4. I plan to use OSX, I presume there are real differences? I guess what I'm unsure about, is it possible to return the phone to the way I have it, settings/programs and all to the state it is right before root, like a Titanium backup? I'm only looking to root to gain wireless tether, I really have any interest in roms (yet) or messing with radio patches. Lastly, once this OTA update comes, and all I do is just gain SU without radio changes or 2.2 roms, can/will I be able to see and update to the official Froyo using stock 2.1 sense without changing anything? What about custom 2.1/sense roms that don't require a radio upgrade? I don't care if I lose root in the process of going official. I looked at Unrevoked Forever, and I just don't like the idea of the lack of ability to revert back if ever need be. Should the ability to root be lost in the update, I know it will be back soon, way too many talented and dedicated people interested VS the ones who designed it. Thanks you for any help and I look forward to finally doing this.
