ok, ive heard rumours of people on ziphone 1.1.4 and upgrading to 2.0.x and then their ipod touch not working. i have a 1st gen ipod touch, and i havent paid for any of the mail, or notes app ect, the upgrade thing they relased you had to pay for, which is why i jailbroke it. now theres 2.0.x and even 2.1 out, i was wondering can i just reboot my ipod to factory settings, then upgrade to 2.1 and then winpwn it? as i have ziphone jailbroken, if i reboot it, does it lose all the ziphone stuff i installed on it, so i can upgrade to 2.1, as i dont want it to crash? i have used search function but cant find anything, cheers in advance for your help.
