Been running it since it was released, works great, no problems. Easy install with update.zip P3 and Team created.
The biggest problems I saw were people thinking they could flash this over 2.1...major no, no.
The other issue was related to losing ROOT, again easy solution, just download the Superuser update found in Rom manager Extras...and flash it at the same time as the 2.3.13 update,ie... 2.3.13update first, then SU update immediately before leaving recovery, then boot into perfectly Rooted 2.3.13..... Simple!!
Very simple easy update, IF you pay attention to details....as with most updates.
