So I see you like your newly installed rom. What performace increase hey. Anyways I think you can install custom themes although I havn't tried it myself. Its all in that topic.
That is all LG P500 threads. Very interresting. It might sound stupid but once you get it sorted you will be a fan. Custom roms opens up features of the phone. It just makes it so much better cause people don't like being limited so those people on xda find ways to make the tings work, stuff the phone makers don't care about.
Ohh yes. The CPU needs to be clocked a bit to get decent performance from it since its not a 1GHz proccessor or something. This might eat the battery sometimes. If you want to manually change the CPU clocking download CPU Master Free.
Just to exceed 729MHz ever!!! It won't break anything but I find that my phone sometimes restart so its not very stable. For me the setting that it has by defaul is best as set by the franco kernel.
And I know you were like wow omg its like a new phone thats the feeling I got with this rom. Its just a amazing rom. But the stock rom is kinda sucky lack of features if you ask me. But I hope you like it.
check that link to keep and eye on updates. I would suggest not to jump to a new update same day its been released. Read the posts first therem might be a bug in there that could effect you in a way. So This rom will most likely be update soon with the new info that the gingerbread update is starting to be released. So watch this space.
