I've read some conflicting opinions, I just want to make sure I don't get locked out of JB/Apple updates, etc. I was thinking of jailbreaking my 3G just to try it out until the new phone comes out. My question is, how can I restore the 3G as new to sell it once I get my new phone? Can I just plug it into iTunes and restore it as a new phone? Or do I have to restore it in a specific mode? Will I have issues if I sync it normally until then while it is jailbroken? When I get my new phone should I just set it up as a new device? I've seen some people mention that the iTunes backups will contain traces of jailbreaking.. One last question - if I do 'wipe' my phone to sell it, will the calendars, contacts, etc. with mobile me stay in tact? I know if you delete one contact, everything sync's, I just wanted to make sure the program is smart enough to not delete everything.
