I've been hoping that someone would do a Sprint ROM like the Verizonguy edition. I was hoping Saridnour or Colonel would do one, since they did such a great job with the AKU3.5 ROMs. But my personal belief (and there is NO basis in fact or hidden knowledge behind this) is that we aren't seeing one from Colonel because he knows or is working on the next official ROM and/or Kitchen. The conspicuous absence of most of the 3.5 ROM makers on this board and their listing in Helmi's "credits" leads me to believe that they are working on something new to release.
I just did my first hard reset since installing WM6 44 days ago and everything seems to be working OK (I only did it because I didn't like the results of the
SP1 update and just removing it didn't help anything).
