Hi, I have a droid eris, and am thinking about getting the 2.1 leak. Just so I don't have to worry about the warranty, I'm hoping I'll have the backup option of going back to the stock 1.5 ROM. However, the only instructions for reverting back to 1.5 seem to be for rooted phones. I don't have a PC (mac instead), so I'm not sure I could do this even if I could figure it out. Is there any other way to restore my phone to factory default OS? Additionally: I have heard that when the legit 2.1 release comes out, I'll be able to update to that whether or not I have the leak. Is this the case? Sorry I don't understand this stuff better. If there's some intro tutorial, please feel free to direct me there. Thanks!!
