I have a jailbroken iphone 4 at 4.0.1. I love the tethering and I've been avoiding updating my phone since doing so. However, I feel like I am missing out on some important updates. Could I get some advice as to how I can update my phone and still maintain the jailbroken/tethering capabilities? I feel like I've skipped so many updates that I might be screwed. Thanks so much! Also, I believe I stored my settings somewhere with Cydia or Rock, if that makes sense.
