Thanks to the hours spent on this board, and to dhlizard and applejuiced, I managed to unlock my iphone using blackra1n/blacksn0w. I have a t-moblie card in there, and it is working like a champ. However, I opted to install cydia at the blackra1n installer menu, but I can't find it anywhere on my phone. I am not sure if this is a common installation problem, or if my app is somehow hidden. Has anyone else ran into this?
