i have had my phone jailbroken and its been 2 days now and not much of a problem... the phone is much better to live with jailbroken...good apps available, have video recording, customised themes and way more that i havent even gone into...the jailbreak seems to be working perfectly fine...i did it two times, just to see how quickly i can do it the second the time...the first time took me 2 hours cuz of misc problems, the second time took me 10 mins total, and im a happy camper....again not much can go wrong jailbreaking, there are always factory restore and etc......
and @doc, what do you mean everytime you put on an ipod...etc....
i have been using app store, and synching with itunes since i jailbroke have no problems at all uptil now...
