You're speaking mindlessly about jail breaking...claiming that 3 of your friends bricked their iPhones from jail breaking them, and i'm telling you that is BS. Did they do something that screwed up their iPhone AFTER jail breaking it? Who knows! It's certainly a possibility, there are a lot of things you can get into that the average joe shouldn't touch after jail breaking an iPhone.
Here's the kicker though...jailbreaking the iPhone didn't make them do those things, it just gave them the ability to. Jailbreaking an i-device doesn't come with an automatic arm twist to customize things that could cause an iPhone to become unresponsive...and even in that scenario, the chance that a full restore would also not work is slim to none.
Take your IT education and cram it if you're going to strut around speaking blindly about how jail breaking iPhones screws them up, because you make it plainly obvious that you haven't the first clue what you're talking about when it comes to such...your post count has nothing to do with it, your asinine comments about jail breaking an iPhone is what speaks worlds about your knowledge on the subject.
And i repeat my comment again, so you can read it clearly...it is nearly impossible...if not FULLY impossible, to brick an iPhone because of the act of jail breaking it.
Correct, sounds like those phones were just in DFU mode or something like that which is easily fixed, I know absolutely nothing about computers and how they work etc. Yet I've been jailbreaking my phone for years now, all the problems I've had were from tweaks that had bugs in them, or mistakes I made, all correctable though.
The biggest problem I ever had with an iPhone was a couple months after I got my 3G in 08 and I didn't even know what jailbreaking was, one night the phone just rebooted by itself and froze up on the Apple logo, I lost all my info, had to restore the phone. I've never had that happen all the years I've been jailbroken, and iOS5 is as fast and reliable as ever running the semi-tethered JB.
All I can say to people who aren't jailbroken is yes, it's not necessary, but boy are you missing out, there's
hundreds of tweaks just in Cydia allowing you to do things with your phone you never imagined. I use stuff that mostly adds to the functionality of the phone, and themes to make it look how I like it to look. The grid of mis-matching icons gets old after 4 years..
