I used Ziphone to jailbreak my day 1 8GB iPhone running 1.1.4. I didn't unlock it as I already had an ATT account. I didn't have to downgrade anything and haven't really had any problems at all since jailbreaking. The occasional crash/weirdness, but nothing really of concern. However, I've been reading numerous posts about how Ziphone can be dangerous and I'm wondering if I should restore my phone and re-jailbreak using something else before I have any problems. I don't want to end up with a dead phone! When I jailbroke (jailbreaked) this shortly after the 1.1.4 update, Ziphone seemed to be the way to go. Not so much anymore. Anyone else in the same situation? Any suggestions and/or help would be most appreciated!! thanks!
