hmmmhh i wouldn't say very unstable, at most unstable, but really more than 10 000 people have done it, i personally know at least 15 people with ipod touches and 3 or 4 with phones, and there is less than a handful of them that have not yet jail broken their ipods, i have yet to encounter any problems with jailbraking mine, yes if you dont know what you are doing they can be bricked, but its possible to un-brick. As well, you cant break your ipod from jail breaking it, you can always back out. Anyways i was just unsure of the context you used stable in. As well with the app store sure their are a hand full, maybe more of decent apps to download, but the majority cost at minimum a couple bucks which is fine, but when you can have access to over a thousand why pay?
