The ROM is amazing - it feels very fast, and of course it has all the great features of CM. I have to see whether it also suffers from the memory leak and slow down over time, but my guess would be no, because that seemed to be a system issue specific to the Huawei ROM.
There are however two small niggles that I would like to bring up:
1) It is missing the APN setting for Ovivo, and others mentioned GiffGaff. Maybe a more recent APN list could be included?
2) If you install it, you have no file explorer (I thought CM includes EFS?) and no backup tool (Go Backup would be nice). So there is no way to install apps from the SD card - you have to get a file explorer from the market first. It would be more convenient to have at least a file explorer included.
And that's it, as I said this ROM is nearly perfect - and the best by far.
