They are, but they also slow your iTouch down. One reason Apple doesn't allow certain apps in the app store is because they require a whole LOAD of memory. Jailbreaking also slows it down, even if you don't have any apps.
Cydia itself is considered to be safe but apps that you may download via Cydia will not have been checked (as they are from Apple's App Store) and so may compromise your personal information without your knowledge.
If you jailbroke it by using cydia all the apps and cydia apps will get deleted
because you need to reinstall cydia
how can i
Yes, many Cydia apps or packages are free. You can simply download them from Cydia. Others must be purchased. To pay for Cydia apps you will need either a PayPal or Amazon account.
If they are apps downloaded from cydia, then no, because cydia apps don't sync with iTunes.
no
Yes they are
Hi! When you jailbreak your iPhone you get a program called Cydia. If u used Cydia then from Cydia u can download Installous and it will let u get free cracked apps
You'll have to open cydia 1 more time and install Cydelete
you can get them for free from "apt.emmersonic.com"
Don't download loads of apps. Cydia alone will most likely not crash your iPhone, but installing many apps increase chances.
