Development is quite slow for this phone which is surprising to me since it is so popular with VM and also carried by Sprint. I think it's slow because most people on VM have never had a smartphone before or development experience. There also seems to be more development for the Sprint Intercept, probably since it's similar to the Samsung Moment. So far I've been able to root and get live wallpapers to work but anything else I try (Deodex, Custom Kernels, ROMS, JIT, etc...) just makes the phone unusable or simply won't boot.
My advise would be to use a task killer only for apps you know you're not using or going to use for awhile (games, navigation, music apps, etc...) and try not to install too many apps.
