Yeah, I know part of it is because it is an older phone now, but I think it is also caused by the multitude of apps on my phone. That being said, is there any way to copy my existing apps to my SD card? Will this make my phone run any faster? I am running the latest version of MIUI so yes, my phone is rooted.
App 2 SD works great. Apps may load slightly slower because SD memory is slower but you'll have more internal RAM. I have all the apps that I can on my SD card.
You can move apps to SD via Settings->Applications->Manage Applications. It probably won't make your device run any faster unless you're completely out of internal storage. It's not like a PC with an IDE hard drive where performance drastically drops as you fill the drive. If you want to improve performance then try another ROM, try overclocking, try a launcher, etc. Look at what's using CPU and RAM.
