I have a Verizon IPhone 4 that I previously jailbroke and it was untethered. I have recently upgraded to the IOS5 and jailbroke the phone again using Redsnow and it is a tethered jailbreak. My questions are about when the phone has to be tethered to the laptop to be rebooted through Redsnow. Do you have to do it every time to download something from Cydia to apply the tweak, app, theme or change? Do you only have to have the phone tethered when you power down the phone from time to time? I rarely turned the phone off in the past and this is my first tethered jailbreak. Thanks for any input and help. This forum has taught me several things and the members have always been there to help.
