An android phone stock is same fun as a jailbroken iPhone. The amount of fun stuff you can do on a jb'd iPhone is immense.
Now, there are two types of Jb's ; tethered and untethered .
The latter one, you don't need to connect phone with laptop everytime you turn it off and on.
After jbing it, you can download cydia and get paid apps for free. Or games. And you can customize the chit out if your phone.
Use Evasi0n for jb.
Warranty is void when jbing, but that is not an issue at all- you can always restore it, forget it, no Apple store in Pakistan anyways lol.
Be careful not to brick your phone- I.e it will work but you have to put it in restore node and that is kinda tricky
