So since jailbreakme.com has been reborn and everything. I have finally jailbroken/unlocked my iPhone 3GS and am planning to sell it on eBay for around 500-600 dollars, after that I will buy a cheap original 2G iPhone and use ZiPhone to change the IMEI # so that I can hide it from AT&T (I don't want to pay for the data plan). My question is, how will I downgrade the firmware to 1.1.4 and has anyone had bad experiences with ZiPhone, I just need to make sure this whole plan will work out for me. I'm pretty sure the latest version of ZiPhone fixed WiFi and YouTube app problems. Also, although I understand ZiPhone is old and all, I heard something about installing Custom Firmware once the IMEI # has been changed with ZiPhone, so that I can basically upgrade to higher firmwares (3.1.3) without changing the baseband/whatever. So yeah, please post and inform me if you have dealt with ZiPhone in the past, and if my plan will go through smoothly.
