Ive been using ZiPhone since January (upgraded to 3.0)....no problems for me but I'll admit, I keep my fingers crossed all the time. I've had to restore twice but I think it's been from installing too many alpha/beta apps. Other than that, I restored in April last time and still running strong....just restore, set up as new phone. Back up your contacts in windows address book and you shouldn't have any problems. This is from MY experience. I've read horror stories from other forum members but its all been from the unlock process. I only jailbreak since Im with ATT. I'd keep a backup of your original firmware though.
