Hey everybody, I have a 3gs on 3.0.1 jailbroken with purplera1n. my modem firmware is 04.26.08 I realize I haven't upgraded in a very long time, I've been absolutely content with the way my phone is that I felt no need. btw i have shsh's stored on cydia for all the new firmwares (or so it says..) My question is, if i want to sell my 3gs, does my old setup do anything for me in terms of value? i dont really know what unlocking is other than you can use other carriers. should I do this? / how can I do this? and what other things can or should I do before I get the new iphone 4. Thanks for the help in advance!
