What is "bricked"? Broken?
And damn, I did not know it could break because of jailbreak. AppleCare won't even cover it?
Don't worry about it, the chance of having a true "bricked" iPhone is slim to none, more likely to win the lottery every day. There are always ways out of recovery mode, just a lot of people don't know and end up thinking their phone is "bricked"... you can see plenty of examples of that alone on this forum when people post up and told how to fix their "bricked" phone lol. But Apple won't repair or do anything with a phone if you bring it in jailbroken.
Cons - like said can't take it as-is to an store for return/replacement/warranty work, have to restore it beforehand. JB in itself causes no issues, but you may use a screwy app or hacked one where you can get glitches, just research what your downloading, I've personally really never had issues over the years. And you can't update to the most recent os till another jb for it is released, but no big deal imo since Apples updates lately seem to cause more issues then they fix lol.
Pros - customizing the phone to your liking not Apples, and some apps/programs actually make the phone better to use yet something simple like SBS... Apple refuses to implement. Here's some good ones from another post:
SBSettings - worth it just to jb for this alone, so much more efficient and better then Apples setup and it integrates perfectly with the notification center... why Apple doesn't do this is beyond me
5/6 icon docks and scrolling dock options
Gridlock to place app's anywhere on pages
Barrel (gives the borring OS new life when switching pages, mine's set to curl and roll away)
FolderEnhancer to replace the dumb Apple folder system, no more restricted # of apps per folder, and can have folders within a folder (great having a game folder that's organized like actions, puzzles, shooting etc.... or same for business folders)
Winterboard/Dreamboard
Quickscroll2 is awesome when browsing
iFile - enough said
Activator - enough said
Zephyr (if you want to use gestures)
Callbar who doesn't love not being interrupted while in the middle of something lol
and I know there's others I'm forgetting
