First I have to give the developers props for taking the time to come up with these 2.2 roms!
Now I have to say, I'm a bit disappointed with the 2 I've tried:
Kaos has Camera FC issues and wasn't as fast as I hoped it'd be.
Neosensikal (v. 15.2 I think I was on?) again wasn't as fast as I was hoping and I had to constantly reboot and battery pull. Especially when using the GPS. Nothing's more annoying than the two times in about 3 weeks that I actually needed the GPS to get me somewhere and it loses satellite lock halfway there. Also, no Google apps. Took me forever to find the Talk.apk. And I had issues updating any app that was saved to the SD card.
I've always had issues with the phone taking forever to load when receiving a call, and neither had Flash support.
Now disclaimer: I LOVE the Sense UI, and the minimalistic feel of Neosensikal just wasn't for me. Some people love that absolute zero bloatware though...
Flashed back to the stock 2.1 ROM. and it's faster than ever. What?! If someone knows a nice, fast Sense-ish rom with Flash support, let me know. Thanks!
