My Tour from eBay should be here Wednesday or Thursday (if there's even mail that day) and I think I want OS 5.0 on it, since I wasn't able to put it on my Curve. Is that a good decision? Also, is there a hybrid version I want? Or do I stick with the original leaked one? The main thing I'm after is the threaded SMS. Could someone please point me in the right direction and give me a download link?
