So I was reading on http://www.iclarified.com/entry/index.php?enid=5885 and it said
Does that mean that Im going to need a computer every single time i turn my phone off and back on?For those with a new iPhone 3GS (updated Bootrom), BlackRa1n only supports a tethered jailbreak. This means that once jailbroken you should not let your battery die. If it does die you will need to reconnect it to the computer and use BlackRa1n to boot it.
