What, not another official OS?
I just installed .244 two days ago. .244 is great so far - reasonable memory useage, reasonable battery usage, stable, good locking of 3g signals.
I believe that I have run every official OS upgrade since the original Roger's OS (.128?), but will probably take a pass on .247. I cannot imagine that it is a material upgrade from .224. Not worth the effort to get everything working as I like it after an OS upgrade.
