Yup... just refer to the official Velocity threads to see what it offers. Speed, much better performance, etc etc. But if they don't want you to do it, let them stay stock I guess.

 

Much faster, especially if flashed in conjunction with drellisdee's JIT. battery life is also much better. More responsive. Def recommend Velocity 0.3 with Drellisdee's GNM_TurboJIT without OC kernel here:http://androidforums.com/ally-all-things-root/180796-gnm_turbo-jit-oc-8-mflops.html
and Velocity 0.3 here: http://androidforums.com/trident/192548-rom-velocity-v0-3-lg-ally-fast-vzb-android-2-1-stable.html

one more thing that helps a lot is LauncherPro (Available in market) QR Code:

 

Yes I whole heartedly agree with Death2all110. The phone transforms from slug to very respectible smart phone after these mods. It also opens up the world as far as customization and tools that help in a significant way.
