I posted something a while back, where I was really complaining hard about the lag this phone was experiencing. And the lag was pretty bad. In the end, I decided to doctor the phone back to factory specs, and I must say, performance improved dramatically. It is certainly not as smooth as the iPhone for instance, but pretty darn close. I don't know if this was related to the various OTA updates, or patches/overclocking being installed/uninstalled, but it is much better after doctoring. If anyone is annoyed with a laggy UI and doesn't have any important text messages that they can't lose, running WebOS Doctor may be helpful. I take back what I said about performance issues.
