Alright, so i have an 8gb iphone(not that memory matters), It had 1.1.4 firmware and whatever baseband Ziphone decided to downgrade to..Anyway, I installed Ziphone on my computer. Alls i did was jailbreak, never unlocked it in my life. So lately apps will start freezing to the point i have to restart my phone to get them to work again. So, does anyone know a way where i can completely restore my iphone. With the upgraded baseband and everything. And if so, what method of jailbreaking should i use next, i need installer but i cant fine winpwn anywhere.

Thanks
