I just got a new iphone 3G that has been factory unlocked and is on version 2.0, but it does not have cydia. I have been told that it may be dangerous to upgrade it as it is one of those phones with the sim adapter soldered inside the phone (see link http://www.iclarified.com/entry/index.php?enid=2093). Someone help me as i cannot do the following -
1) Sync on itunes 8.0 without using an AT&T sim. I don't have issues when syncing on itunes 7.7.
2) No Cydia
