Ever wanted to know how to change the icons of a particularly ugly app? Well, if you're Jailbroken and have SSH access you're in luck! Resident theming genius, Ally (iMuggle on TiPb Forums and in the ">Twitter) has begun collecting her excellent tutorials into one easy to browse place. Here's a sample:
you need to know how to do a few things in order to do this. After jailbreaking, you need to know how to SSH into your phone. If you're not familiar with SSH, you need to get familiar with that first. *Note: Unless you feel completely comfortable doing this, I don't recommend it. Point being, SSH'ing will give you access to ALL of your iPhone's core files, so deleting/editing certain files could be disastrous if you don't know what you're doing. If you're still reading, and you're okay with all of this, continue on.
So, fair warning, that's why we call these iPhone Ninja tips. They're not for the casual user -- hard core only.
If you're interested and eager, however, give Ally's tutorials a look and let her (and us!) know your results.
