So basically, I just received a 16 GB iPhone 4, which will seem kind of silly, seeing as how everyone's saying that the next iPhone is looking to come out in September. But no biggie, I guess I'll have to soak up these supposed last two months of having the latest iPhone. My biggest issue with the iPhone 4, along with every other iPhone produced, is the lack of capability to customize. The Retina display is great, as well as the interface, but I get tired of looking and hearing the things that the iPhone 4 came with and no more. The SMS text tones and ringtones -- I don't have the option to change these to anything other than what the iPhone offers me, and I really don't want to have to pay every time I want a new ringtone. After a brief research session, I learned that one could not change these particular things without jailbreaking it, so I decided to look into it. However, being a complete noob with things concerning the "unofficial," I am worried and questioning a few things. 1. How does one go about jailbreaking the iPhone? I've heard of programs, but I'm not sure how it works. Do you just open the program and let it do the work? What program is most used or recommended? 2. What are the risks of jailbreaking your iPhone? Is there a chance of damaging my iPhone internally, messing up software and such? 3. Other than being able to customize more freely and free apps, what are the perks of having a jailbroken iPhone/iPod/iPad? Thanks to anyone who actually read through this long post, and even more to anyone who can help.
