I am using desire (Froyo) very happily except interal storage usage.
So, I have some interests and questions about rooting.
1. In Froyo (non-rooting) , some parts of app is stored in sdcard but not all.
Will rooting make all parts of app move to sdcard ?
In terms of internal storage usage, will rooting give me some benefit over froyo ?
2. If I root my phone, shoud I flash my phone with another customized ROM ?
3. If I root my phone, will my setting and apps and data disappear ?
is there any backup methods ? is My backup pro enough to restore my setting ?
4. If I fail to root my phone, can I recover to my original state ?
Some advices make me very happy and thank you in advance.
